Given a triangle with: a =<br> 150, A = 75°, and C = 30°<br> Using the law of sines gives: c = 0
koban [17]

Answer:

c = 77.6

Step-by-step explanation:

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

\dfrac{\sin A}{a} = \dfrac{\sin C}{c}

\dfrac{\sin 75^\circ}{150} = \dfrac{\sin 30^\circ}{c}

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

c = \dfrac{150 \sin 30^\circ}{\sin 75^\circ}

c = 77.6

You are correct. Good job!
