Question

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

Answer 1

use pythagoras theorem

20^2 = 8^2 + x^2 where x = length of th other leg

x^2 = 20^2 - 8^2 = 336

x = sqrt 336

= 18.3 to nearest tenth

Answer 2

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
