Question

Find x y and z in this probelm

Answer 1

For the top shape, x = 11, y = 10 and z = 14.

Start with the equation: 11y + 7y = 180 because those two angles are supplementary. Solving that will give you that y = 10.

The angle that is labelled 7y is therefore 70 degrees. We can write the following equation will the 5x because it is corresponding to the 70 degree angle.

5z = 70
z = 14

And we can also write and solve for the x, using the 70 degree angle.
70 + 10x = 180
10x = 110
x = 11
