Question

4) Determine the measure of each unknown exterior angle.

Answer 1

The answer you’re looking for is x = 90 degrees

Answer 2

Explanation:

Angle on a straight line add up to 180

therefore the value for x

x + x = 180 not: vacuum of interior angle have the same side therefore = x

2x = 180

2x/2 = 180/2

x =90
