Question

11. Angles 1 and 2 are supplementary. Angle 2 is 1/3 the size of angle 1. What

are the degree measurements of each angle?
⚫️67.50 and 22.5°
⚫️22.5° and 90°
⚫️60 and 120°
⚫️135° and 45°

Answer 1

90 for choice 1, 112.5 is for choice 2, 180 for choice 3, and 180 for choice 4.

Explanation:

67.50 and 22.5 is a complementary angle because it adds up to 90 degrees.

22.5 and 90 added is 112.5 which is an obtuse angle

60 and 120 added is a supplementary angle because 60 + 120 is 180

135 and 45 is also a supplementary angle because 135+45 = 180
