Question

Use the picture below to answer questions 13a and 13b.

13a) What is the measure, in degrees, of angle 1? Explain how you determined the measure of angle 1.

13b) What is the measure, in degrees, of angle 2? Explain how you determined the measure of angle 2

Answer 1

13a: Measure of angle 1 is 120 degrees

13b: Angle 2 is 60 degrees

Explanation:

Angle 1 is alternate exterior (so in a parallel pair they are equal) to the angle on line m given as 120 deg.

Angle 2 is 180 minus 120= 60 Sum of the two angles must equal 180.
