Question

Solve for b.
105
15
2
Round your answer to the nearest tenth

Answer 1

Explanation:

Use the Law of Sin:
`(a)/(sinA) = (b)/(sinB) =(c)/(sinC)`

`(b)/(sin 15) = (2)/(sin105)`

Cross Multiply so sin105 x b = 2 x sin15

divide both sides by sin105 to get. b = (2 x sin15)/sin105

b = (0.51763809)/(0.9659258260

b = 0.535898385. round to nearest tenth, b = 0.5
