Question

What is the measure of angle x? Round to the
nearest tenth. .
28
21
xº

Answer 1

x =53.1

Explanation:

Since this is a right triangle, we can use trig functions

tan theta = opp side/ adjacent side

tan x = 28 /21

Take the inverse tan of each side

tan ^-1 (tan x) = tan ^-1 (28/21)

x = 53.13010235

Rounding to the nearest tenth

x =53.1
