Question

Find the unknown sides of the triangle

Answer 1

Explanation:

This requires the use of the Pythagorean Theorem.

Givens

a = 2√2

b = 2√5

Solution

a^2 = ( 2√2)^2 = 4 * 2 = 8

b^2 = (2√5)^2 = 4 * 5 = 20

c^2 = ?

c^2 = 8 + 20 = 28

c = sqrt(28) = sqrt(2*2 * 7) = 2 * sqrt(7)

That could be your answer, but it is not listed. If you need a number, that would be 5.29 which is not correct.
