Question

Find c.
Round to the nearest tenth:

Answer 1

0.5 cm

Explanation:

C = 15°

B = 105°

b = 2 cm

Applying the law of sines, we have:

`(2)/(sin(105)) = (c)/(sin(15))`

Cross multiply

`sin(105)*c = 2*sin(15)`

Divide both sides by sin(105)

`c = (2*sin(15))/(sin(105))`

`c = 0.5 cm` (nearest tenth)
