Solve for the missing measure. round your answer to the nearest tenth.

Using the Pythagorean theorem:

20^2 = 8^2 + X^2

400 = 64 + X^2

X^2 = 400 - 64

X^2 = 336

X= √336

X = 18.3

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

your answer is the frist one
