The sum of all the angles on the straight line is 180 degrees.
x + y + z + 66 = 180
x + y + z = 114
But x, y and z have the same value
x + x + x = 114
3 times x = 114
x = 114/3 = 38
z = 38
x + z = 38 + 38 = 76 degrees
x + y + z + 66 = 180
x + y + z = 114
But x, y and z have the same value
x + x + x = 114
3 times x = 114
x = 114/3 = 38
z = 38
x + z = 38 + 38 = 76 degrees
