Question

Solve for b. Round your answer to the nearest whole degree.
5.1
bº
3.6
100

Answer 1

b =44

Explanation:

We need to use the law of sines to determine b

sin b sin 100

---------------- = ----------------

3.6 5.1

Using cross products

5.1 sin b = 3.6 sin 100

sin b = 3.6 sin 100 / 5.1

Taking the inverse sin of each side

b = arcsin ( 3.6 sin 100 / 5.1)

b = 44.03984209

To the nearest degree

n = 44
