Question

If b=5 , the angle C=50 and the angle A=50 find the other angle B and the remaining sides and . Give your answer to at least 3 decimal places.

Answer 1

Angle B = 100, (the sum of all three is 180)

apply the Sine Law, I will do one, you do the other

c/sin50 = 5/sin80
c = 5sin50/sin80 = 3.889
