Question

Given a triangle with: a =
150, A = 75°, and C = 30°
Using the law of sines gives: c = 0

Answer 1

`c = 77.6`

Explanation:

You may have entered the measure of a side as the measure of an angle.

`(\sin A)/(a) = (\sin C)/(c)`

`(\sin 75^\circ)/(150) = (\sin 30^\circ)/(c)`

`c\sin 75^\circ = 150 \sin 30^\circ`

`c = (150 \sin 30^\circ)/(\sin 75^\circ)`

`c = 77.6`

You are correct. Good job!
