Question

Find x, the third side of the triangle.

Answer 1

5

Explanation:

By using the Pythagorean theorem, you can solve for x

a^2 + b^2 = c^2

Where in this scenario a = 12 and c = 13.

B isn't known, so you use the other bits of information in the Pythagorean theorem, which will give you 5

12^2 + 5^2 = 13^2

169 = 169
