Question

Determine the missing angle measure.

Answer 1

X=38 degrees

Explanation:

A straight line is 180 degrees so to find the missing part you can do 180-142.

That way you get the missing angle measurement.

Answer 2

38°

Explanation:

We have supplementary angles, which mean they add up to 180°, so we can simply solve for x° by doing 180°-142°=38°
