Question

Find the value of the sine for angle A

Answer 1

b. 3/5

Explanation:

Using the pythagorean theorem, side AB is 100 m long.

Sine equals opposite over hypotenuse. In this case CB (60) is the opposite and AB (100) is the hypotenuse.

Sine for angle A = 60/100 = 3/5

Answer 2

B

Explanation:

sin=opposite/Hypotonouse

80²+60²=hyp²

hyp=100

sinФ=60/100=3/5
