Question

Pythagorean theorem to find the side of 16 20

Answer 1

Answer: 12

Step-by-step explanation:

Although you have not included which value is the hypotenuse or if they are legs, I will assume the hypotenuse is 20, due to the triangle appearing to be a multiple of the standard 3-4-5 triangle.

The pythagorean theorem is a^2+b^2=c^2, where a and b are the legs and c is the hypotenuse.  Thus, plug in the values to get:

$16^2+b^2=20^2$

$256+b^2=400$

$b^2=144$

$b=12$
