Question

Use a calculator to approximate the measure of the acute angle A to the nearest tenth of a degree. sin A = 0.7793

Answer 1

The measure of acute angle A to the nearest tenth of a degree is 51.2°

Measure of angles

From the given information, we are to determine the measure of the angle.

The angle we are to determine its measure is acute angle A

From the given information, we have that

sin A = 0.7793

Thus,

A = sin⁻¹(0.7793)

Using calculator

A = 51.1965°

A ≅ 51.2°

Hence, the measure of acute angle A to the nearest tenth of a degree is 51.2°
