Best ResponseYou've already chosen the best response.0Lol, I know it's kind of hard to read.

Best ResponseYou've already chosen the best response.1I dont know where the 2 goes, lol.

Best ResponseYou've already chosen the best response.0There was no 2 and it was 5.2

Best ResponseYou've already chosen the best response.1Thers a more clearer version.. As you can see, this looks like an isosceles.

Best ResponseYou've already chosen the best response.0Ahh, Yes it kinda looks like a triangle split in two

Best ResponseYou've already chosen the best response.1Now..because of this one rule..lol, sorry forgot the rule, but remember its function, but it stated that that line in the middle, i think altitude its called, not sure, that separates the triangle, makes the two halves equal.

Best ResponseYou've already chosen the best response.1So, basically, that means: dw:1337041876443:dw

Best ResponseYou've already chosen the best response.0Ok, Would I use the a2 + b2 = c2 and the a=1/2bh?

GOODMAN

Best ResponseYou've already chosen the best response.1Yes..I have found all the necessary lengths, all you need to do is plug it in to your formula.

Best ResponseYou've already chosen the best response.0Ok, Would it be like this: 7^2 + 7^2 = 5.2^2?

28Tylerr

Best ResponseYou've already chosen the best response.0Or would you add the 2 5.2's to make 10.4?

GOODMAN

Best ResponseYou've already chosen the best response.1Use Pythagorean Theorem. Our hypotenuse, or "c" is 7 our leg 1 or "a" is 5.2 we need to find leg2 or "h"

28Tylerr

Best ResponseYou've already chosen the best response.0Ok, So how would I set that up?

GOODMAN

Best ResponseYou've already chosen the best response.1\[a ^{2}+b ^{2}=c ^{2}\] \[(5.2)^{2}+b ^{2}=7^{2}\] \[27.04+b ^{2}=49\] \[27.04Subtract \] \[b ^{2}=4927.04\] \[b ^{2}=21.96\] \[b=4.7\]

Best ResponseYou've already chosen the best response.1Our "b" will substitute as our "h" or height.

Best ResponseYou've already chosen the best response.1So, now we have all the components of our triangle. A=1/2bh A=1/2(10.4)(4.7) A=1/2(48.88) A=24.44

Best ResponseYou've already chosen the best response.0Would that be my answer and my answer for my area

GOODMAN

Best ResponseYou've already chosen the best response.1Yes..that would be your area.

28Tylerr

Best ResponseYou've already chosen the best response.0Mhmmk, can you help me with 1 more like this?

GOODMAN

Best ResponseYou've already chosen the best response.1Okay..but I gotta hurry. I have some trig functions, lol.

GOODMAN

Best ResponseYou've already chosen the best response.1Like that? Is it isosceles as well?

GOODMAN
 2 years ago
Best ResponseYou've already chosen the best response.1Okay, because of the altitude, we can also determine this..dw:1337042961699:dw

GOODMAN

Best ResponseYou've already chosen the best response.1Now.. We have our formula. A=1/2bh Our Base: 16 And our height: 5

28Tylerr

Best ResponseYou've already chosen the best response.0Can you show me some work for that plz on both? (:

GOODMAN

Best ResponseYou've already chosen the best response.1A=1/2bh A=1/2(16)(5) A=1/2(80) A=40

28Tylerr

Best ResponseYou've already chosen the best response.0What about for a2 + b2 = c2

GOODMAN

Best ResponseYou've already chosen the best response.1We didn't need the Pythagorean Theorem, because we had all the necessary lengths to find the Area.

28Tylerr
 2 years ago
Best ResponseYou've already chosen the best response.0Oh ok so all I needed was the Area because

28Tylerr
 2 years ago
Best ResponseYou've already chosen the best response.0I had all of the lengths

GOODMAN

Best ResponseYou've already chosen the best response.1Yes..but the first one, we needed the height, and we used the Pythagorean Theorem to find it. In this problem, we already had everything we needed to find the Area.

Best ResponseYou've already chosen the best response.0Ok, I thank you for all of the help Goodman. Hopefully you can help me some more some other time. Thank You (:
