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
