Question

For the right triangle shown, the lengths of two sides are given. Find the third side. Leave your answers in simplified, radical form. Type your answer in the answer box provided.

a = 4, b = 4, c =

Answer 1

The correct answer is c = 4√2.

Answer 2

This is a simple Pythagorean theorem, which says that c2 = a2 + b2
So let us just apply it here:

c^2 = 4^2 + 4^2
c^2 = 16 + 16
c^2 = 32
c = √32
c = √2*16
c = 4√2

The correct answer is c = 4√2.
