Supplementary

300
What is the supplementary angle of 103 degrees?
77 degrees 180 - 103 = 77
300

149 degrees

300

Angle A and B are corresponding angles. Angle A is (x + 30) degrees. Angle B is 2x degrees. Solve for x.

x = 30

400

What is the difference between an acute and an obtuse angle?

An acute angle measures less than 90 degrees while an obtuse angle measures more than 90 degrees.

400
What is the supplementary angle of 13 degrees?
167 degrees 180 - 13 = 167
400

Angle a and b are complementary. Angle a is 35 degrees. What is the measure of angle b? 

55 degrees

400

Angle x and angle y are vertical angles. Angle y measures 149 degrees. What is the measure of angle x?

149 degrees

400

Angle A and B are consecutive exterior. Angle A is x degrees. Angle B is 2x degrees. Solve for the measure of each angle (in degrees)

a = 60 degrees, b = 120 degrees

500

Are all complementary and supplementary angles always adjacent? Explain.

No. While they are normally adjacent, they could also be separate. What's important is that two angles add to 90 degrees to be complementary or add to 180 degrees to be supplementary.
