The angle measure of a triangle are shown in the diagram.

What is the value of z?

1 answer

The value of z is 40 degrees.

This can be determined by using the fact that the sum of the angle measures in a triangle is always 180 degrees.

Therefore, we can set up an equation: y + 70 + z = 180

Substitute the known values:
110 + z = 180

Solving for z:
z = 180 - 110 = 70

So, z = 70 degrees.
