Best ResponseYou've already chosen the best response.1okay well the theorem is \[z^2=x^2+y^2\] and you know everything has to be an integer (whole number)

Best ResponseYou've already chosen the best response.1you can just try different values. For instance for the first one i might try z=51 and x=24. so 51^2=24^2+y^2. Solving i get y=45. So this works

Best ResponseYou've already chosen the best response.0@cherio12 can you try #19 plz

Best ResponseYou've already chosen the best response.1you just have to play with the numbers. I first tried \[z^2=25^2+20^\] but i got z= 32.0156..so this didn't work next i tried \[25^2=20^2+y^2\] y=15 (this is an integer) so it checks out

Best ResponseYou've already chosen the best response.0thats the answer in the book so i should be able to learn off your 2 answers

Best ResponseYou've already chosen the best response.0wait so on 18# i got 2601=576+y2 then do i get y by itself? @cherio12

cherio12

Best ResponseYou've already chosen the best response.1yes. you should go 2601576=y^2. then take the squareroot of both sides to just get y

Best ResponseYou've already chosen the best response.0ok how do you know were to put the numbers on the equation?

Nick2019

Best ResponseYou've already chosen the best response.0wait oh i see you said move them around and it has to be a whole number

cherio12

Best ResponseYou've already chosen the best response.1yup, its always (leg)^2+(leg)^2=(hypotenuse)^2

Best ResponseYou've already chosen the best response.0thanks man! helped alot

Best ResponseYou've already chosen the best response.1its commonly written as x^2+y^2=z^2

Best ResponseYou've already chosen the best response.0wait so on # 20 i got 91.82592222ect

cherio12

Best ResponseYou've already chosen the best response.1okay so that means you picked the wrong combo of hypotenuse and legs. try another combo (by the way the hypotenuse will always be the largest of the 3 numbers)

Best ResponseYou've already chosen the best response.0so set it up as x2= 96 + 28?

cherio12
 2 years ago
Best ResponseYou've already chosen the best response.1i would try \[96^2=x^2+28^2\]

Nick2019

Best ResponseYou've already chosen the best response.0but i still will get that 91.etc right?

cherio12

Best ResponseYou've already chosen the best response.1i was just showing you the triangle to help show what i meant by x, y and z

Nick2019

Best ResponseYou've already chosen the best response.0i know im saying when i get x by its self and take 9216 and square it i get that 91.00202 number

cherio12

Best ResponseYou've already chosen the best response.1o you mean for the 96, 28 problem?

cherio12
 2 years ago
Best ResponseYou've already chosen the best response.1\[96^2=x^2+28^2\] \[9216=x^2+784\] \[9216784=x^2\] \[x=\sqrt{8432}\] x=91.8259 so this way didn't work.

cherio12
 2 years ago
Best ResponseYou've already chosen the best response.1i would then try \[z^2=96^2+28^2\]

Nick2019
 2 years ago
Best ResponseYou've already chosen the best response.0but you would still get 91.8259 right?

cherio12

Best ResponseYou've already chosen the best response.1you add 96^2 and 28^2 in this example instead of subtracting them (like we tried before)

Best ResponseYou've already chosen the best response.0now i see thakns agian lol

Nick2019

Best ResponseYou've already chosen the best response.0hey can you help @cherio12 with # 23

cherio12

Best ResponseYou've already chosen the best response.1okay so i first tried z^2=72^2+75^2 But i got z=103.966 so that's not right then i tried 75^2=x^2+72^2

Nick2019
 2 years ago
Best ResponseYou've already chosen the best response.0ok i did the first but didnt try that one what did you get?

Nick2019

Best ResponseYou've already chosen the best response.0can you show how you did that?

cherio12

Best ResponseYou've already chosen the best response.175^2=x^2+72^2 solve for x

Nick2019

Best ResponseYou've already chosen the best response.0hey @cherio12 for #24 you you do the same?

cherio12

Best ResponseYou've already chosen the best response.1yes, your two legs are 6 and 3

Nick2019
 2 years ago
Best ResponseYou've already chosen the best response.0so would it be 6(2)=3(2)+x2

cherio12
 2 years ago
Best ResponseYou've already chosen the best response.1by(2) do you mean you are squaring it?

Nick2019
 2 years ago
Best ResponseYou've already chosen the best response.0no 6 to the power 2 like 6*6

cherio12
 2 years ago
Best ResponseYou've already chosen the best response.1that means squaring, but yes that is correct

Nick2019

Best ResponseYou've already chosen the best response.0i tried both ways and got not a whole number

cherio12

Best ResponseYou've already chosen the best response.1I don't believe you are supossed to get an integer for this problem

Nick2019

Best ResponseYou've already chosen the best response.0ya that was my second way

Nick2019
 2 years ago
Best ResponseYou've already chosen the best response.0so would you set up # 25 and # 26 the same way?

cherio12
 2 years ago
Best ResponseYou've already chosen the best response.1yes for 25, but for 26 you will use a ratio

cherio12

Best ResponseYou've already chosen the best response.1i gotta go eat..be back later

Nick2019
 2 years ago
Best ResponseYou've already chosen the best response.0ok when you get back can you explain ratio?

cherio12

Best ResponseYou've already chosen the best response.1okay well for starters find the other leg on the 5,3 triangle

Nick2019
 2 years ago
Best ResponseYou've already chosen the best response.0wait on the # 25 its just 11 and x so is it 121 then sqare root answer is 11?

cherio12
 2 years ago
Best ResponseYou've already chosen the best response.1no, there are two 11 sides

Nick2019
 2 years ago
Best ResponseYou've already chosen the best response.0oh i see cuase of that line thingy

cherio12
 2 years ago
Best ResponseYou've already chosen the best response.1no for 25, it is 11^1+11^2=x^2

cherio12
 2 years ago
Best ResponseYou've already chosen the best response.1does that make sense why?

Nick2019
 2 years ago
Best ResponseYou've already chosen the best response.0yes i just didnt try that way and remember there not whole numbers

Nick2019
 2 years ago
Best ResponseYou've already chosen the best response.0so how do you do #26 is it 2 problems in 1

cherio12
 2 years ago
Best ResponseYou've already chosen the best response.1find the other leg in the 5,3 triangle first

Nick2019
 2 years ago
Best ResponseYou've already chosen the best response.0now do the other triangel?

cherio12
 2 years ago
Best ResponseYou've already chosen the best response.1now we can use like triangle ratios 4/5=7/x

Nick2019
 2 years ago
Best ResponseYou've already chosen the best response.0so 4 sqare + 5 square = 7sqare?

cherio12
 2 years ago
Best ResponseYou've already chosen the best response.1just ratio, just division

Nick2019

Best ResponseYou've already chosen the best response.0oh ok wow being sick for one day of notes can rweally heart you

Nick2019

Best ResponseYou've already chosen the best response.0wait # 28 its 2x and 2x+4 and the length of the hypot is 4x4

cherio12

Best ResponseYou've already chosen the best response.1yes, just apply the Pythagorean theorem
