SOLUTION
Angle C is 133 degrees
From the image , angle c is the same as angle a, reason been that they are vertically opposite angles and they are always equal.. let us call angle c and a = x
Angle b = 47 degrees, because they are both vertically opposite angles, and they are always equal.
Angle c + angle a + angle b + 47 = 360 ( sum of angles at a point)
x + x + 47 + 47 = 360
2x + 94 =360
2x = 360-94
2x =266
x= 266/2
x=133 degrees
So angle C is 133 degrees
