Question

What is the side length b in the triangle below?

Answer 1

Heres the triangle.

Answer 2

use the pythagorean theorem, since it is a right triangle; a^2 + b^2 = c^2
so since a = 20 and c= 26; we plot it in
20^2 + b^2 = 26^2
400 + b^2 = 675
b^2 = 675 - 400
b^2 = 276
b = *sqrt(276
b = 16.6132 or b = 16.6, if rounded
