Question

Find the measure of the indicated angle to the nearest degree.

A. 40
B. 57
C. 33
D. 50

Answer 1

50(Option D)

Explanation:

Trigonometry

Inverse trig for this

So we are given adjacent and opposite legs for this part. So tangent is used except because we are finding angle(tan^-1 is used) tan^-1 is not 1/tan

tan^-1(56/47)

We get 49.993744 and so on

So rounded to the nearest degree, that is 50.
