Question

Solve the triangle.

A = 32°, a = 19, b = 12

Answer 1

so you can find the size of angle B by using the law of sines

\[\frac{\sin(32)}{19}=\frac{\sin(B)}{12}\]

just solve for B

when you have B you can find C by angle sum of a triangle

to find the length of side c, use the law of sines again

hope this helps

Answer 2

Why do I do (sin(32)/19) rather than (19/sin(32))?

Answer 3

you can... the law of sines works either way

but the way I've written it, your unknown, B, is in the numerator

Answer 4

you will need to do it that way to find the side c
