Find c if a = 7 and b = 9.
Right triangle with sides a, b, and c. Side c is opposite the right angle.
A. c = 16
B. c = 4
C. c = 3 times the square root of 7
D. c = the square root of130

Best ResponseYou've already chosen the best response.0um like this A^2 +B^2= C^2

Best ResponseYou've already chosen the best response.0You got it. You are given A and B. Let's do it. 7^2 + 9^2 = C^2.

Best ResponseYou've already chosen the best response.0@somebodys_heartbrake that's exactly the same question as the previous one except this one has different values. And now you don't know square roots and squaring which should of been taught in primary/elementary school.

Best ResponseYou've already chosen the best response.0Alright so far we know that 130 = C^2. What's C???

Best ResponseYou've already chosen the best response.0I think it's a different question, but then it's just using the same format as the previous one.

Best ResponseYou've already chosen the best response.0Alright so far we know that C^2 = 130. Let's find C. Do you know how to find square roots, or are you a little bit rusty?

Best ResponseYou've already chosen the best response.0Do you know the square root of say 9? Or do you know nothing about square roots? I don't care either way so just be honest

Best ResponseYou've already chosen the best response.0haha alright :) Let's learn some square roots then. I'm not a math teacher but i'll try my best.

Best ResponseYou've already chosen the best response.0So basically a square root is " What number multiplied by itself will give me this number"

Best ResponseYou've already chosen the best response.0Anyway another way to look at square roots is "What number SQUARED, equals this number?" So lets look at \[\sqrt{4}\] . 2 squared . Aka 2*2 = 4

Best ResponseYou've already chosen the best response.0wouldnt it be 3 to the first 1 u asked

Best ResponseYou've already chosen the best response.0Yeah exactly. 3*3 = 9. So the square root of 9 is three.

Best ResponseYou've already chosen the best response.0Alright it works with letters or "variables" too. What's the square root of \[\sqrt{x^2}\] ?

Best ResponseYou've already chosen the best response.0Nice. X*X = X^2. How about something that applies to us. What is the \[\sqrt{C^2}\]

Best ResponseYou've already chosen the best response.0Nailed it. So we left off at \[C^2 = 130\]. What happens if we take the square root of both sides?

anonymous

Best ResponseYou've already chosen the best response.0Write it out for me. Put a square root symbol around both sides.

Best ResponseYou've already chosen the best response.0Alright so we are just going to draw a square root sign around both sides. You can do it. I'll do it first. \[\sqrt{C^2} = \sqrt{130}\]

Best ResponseYou've already chosen the best response.0@somebodys_heartbrake wants to know how to write a square root sign like what @RandomFriend did above. I don't think @somebodys_heartbrake knows how to use the equation editor.

Best ResponseYou've already chosen the best response.0I dont care if you don't know how to use the equation thing. As long as you get it. Do you see how i got my equation above?

anonymous

Best ResponseYou've already chosen the best response.0Alright I'ma move on. from here \[\sqrt{C^2} = C. \]. This givese us C = sqrt(130). Which was one of our answers I believe.
