Question

What’s the value of x??

Answer 1

x=10

Explanation:

First split the triangle in half. The lengths and width are: 1/2x, 12, and 13.

Again, you use the pythagorean theorem (
`a^(2)`+
`b^(2)`=
`c^(2)`) except you reverse it to find
`a^(2)`.
`c^(2)`-
`b^(2)`=
`a^(2)` plug in the numbers (169-144=
`a^(2)`) ----> a=5----> the thing is you want to find x, which is the length of the whole triangle, not the half one. So then you multiply by 2 to get x=10
