The sum of angles in a triangle is 180 degree
we are given with two angle and asked to find the third angle x
First angle + second angle + third angle = 180 degree
Angle A + angle B + Angle C = 180
angle A = x
angle B = 75
angle C = 50
x + 75 + 50 = 180
x + 125 = 180
Subtract 125 from both sides
x= 55 degree
So value of x= 55 degree
