The measures are;
y = 140 degrees
x = 50 degrees
To determine the measure of the angles, we have to know that;
- Complementary angles sum up to 90 degrees
- Supplementary angles sum up to 180 degrees
- Angles on a straight line is 18- degrees
- Angle at right angle is 90 degrees
Then, we can deduce from the diagram that;
z + 40 + 90 = 180
collect like terms
z = 180 - 130
z = 50 degrees
Then, y = 50 + 90 = 140 degrees
x = 50 degrees, vertically opposite angles
