Question

Help anyone can somebody explain the answer please

Answer 1

c^2 = a^2 + b^2
c^2 - b^2 = a^2
SquareRoot (c^2 - b^2) = a

SquareRoot (16^2 - 8^2) = a

SquareRoot (256 - 64) = a

SquareRoot (192) = a

SquareRoot (64) x SquareRoot (3) = a
8x SquareRoot (3) = a
Answer is Choice D

Answer 2

D

Explanation:

8^2+x^2=16^2
