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!
