2 23 66 61 SolutionAngle C 66 deg Angle B 61 deg Angle A

Solution

Angle C = 66 deg

Angle B = 61 deg

Angle A = 180 -66 -61 = 53 deg

Lets find the sides of the triangle using sine rule:

side oppostie to angle C is c

side opposite to B is b

23/sin61 = c/sin66

c = 23*sin66/sin61 = 24.02

a/sin53 = 23/sin61

a = 21

We have all the sides: a, b, c , Angle A, Angle B and Angle C
