Question

Please help due tmr. Find c.
Round to the nearest tenth:

Answer 1

c = 14.9 cm

Explanation:

Applying the Law of Sines, we would have the following:

c/sin(C) = b/sin(B)

c = ??

C = 180 - (150 + 12) = 18°

b = 10 cm

B = 12°

c/sin(18) = 10/sin(12)

Multiply both sides by sin(18)

c = (10*sin(18))/sin(12)

c = 14.9 cm (nearest tenth)
