Question

Can someone help me solve for x?

Answer 1

@Michele_Laino could you help me solve for x?

Answer 2

Are you solving for the area or something?

Answer 3

No I'm supposed to solve for the missing side. I know how to do that but I can't figure out what x is.

Answer 4

well what's the equation for adding up the sides?

Answer 5

I'm not sure. I know that a^2 + b^2 = c^2 can be used to find the base of the triangle. I'm just not sure if I'm supposed to solve for x before that.

Answer 6

No. You use that equation to solve for x.

Answer 7

ask a qualified helper. I am not sure sorry.

Answer 8

oh thanks Zelda

Answer 9

\[20^2 = (x^2) + (5x)^2 => 400 = x^2 + 25x^2 => 400 = 26x^2\]

Answer 10

Okay so 400 = 26x^2 and then I just find the square root of 26x^2? And then divide 400 by what I get?

Answer 11

You have to divide both sides by 26, then take square roots.

Answer 12

Oh okay. So 400 / 26 = 26x^2 / 26
15.4 = x^2

Answer 13

@Zelda would I then find the square root of 15.4 and x^2?

Answer 14

@texaschic101 do you think that's what I should do?

Answer 15

Yes.
