Help me please! :( 1. If Z2 measures 120°, what is the measure of Z1? Explain how you found the measure of 21.

60

Step-by-step explanation:

Angles 1 and 2 are supplementary, which means that their sum is 180 degrees.

180 - 120 = 60

Angle 1 is 60 degrees

angles 1 and 3 are vertical angles, meaning that they are equal to each other. to solve this you may set angle 1 and 3 equal to each other and just solve for x like

110 = 2x + 10

100 = 2x

50 = x

check:

110 = 2* 50 + 10

110 = 100 + 10

110 = 110

hope this !
