If a=8, the angle C=50 degrees and the angle A=35 degrees find the other angle B and the remaining b and c sides. Give your answer to at least 3 decimal places.

I will assume you have a triangle.

Because of the 180° angle sum, angle B = 95°

now use the Sine Law twice, I will do the first

b/sinB = a/sinA

b/sin95 = 8/sin35

b = 8sin95/sin35 = 13.894

do the third side the same way
