Using Law of Sines: Need Help

Question

1. alpha=70 Degrees
Beta=38 Degrees
a=35

Answer 1

I assume you are trying to find the other two sides of the triangle?

You have two angles: 70 and 38, so the 3rd angle = 72

a/sin 70 = b/sin 38 = c/sin 72

35/sin 70 = 37.246

now you have b/sin 38 = 37.246

and so on for c
