Question

Let angleQ be an acute angle such that cosQ =0.32 Use a calculator to approximate the measure of AngleQ to the nearest tenth of a degree

Answer 1

Hi there! The answer is about 71.3°.

If
$\cos(q) = 0.32$

Then
$q = { \cos(0.32) }^{ - 1} = 71.337$

Hence, the measure of angle Q is about 71.3°

Answer 2

CosQ = 0.32
Q = cos-1(0.32)
Q = 71.3°
