Question

Determine the measure of angle A, to the nearest degree.

a) sin A = 0.2896
b) tan A = 4.7046​

Answer 1

(a) 17°

(b) 78°

Explanation:

(a) sin A= 0.2896

to calculate for "A" check for sin inverse of 0.2896

A= sin^-1(0.2896) = 16.83

to the nearest degree A= 17°

(b) tan A = 4.7046

A= tan^-1(4.7046)

A = 77.99

to the nearest degree A = 78°
