Answer:
Step-by-step 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.
