Question

Find angle b to the nearest tenth of a degree if cos B = 0.8926 and angle b is an acute angle

Answer 1

If cos B= 0.8926 ==> means arcos(0.8926) ===> B=26.7 or 26 dedree

Answer 2

The value of angle B will be 26.7 degrees.

What is trigonometry?

The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle termed trigonometry.

Given that:-

• cos B = 0.8926

The angle B will be calculated as follows:-

Cos B= 0.8926

B = arcos(0.8926)

B=26.7  

Therefore the value of angle B will be 26.7 degrees.
