What is the measure of 8? 120° 90° 60° 180° what type of angles are 1 and 5? vertical supplementary corresponding complementary

< 8 = 60

<1 and <5 are corresponding angles

Step-by-step explanation:

<2 = <3  vertical angles

<3 = <6  alternate interior angles

<6 + <8 = 180  supplementary angles

120 + <8 = 180

Subtract 120 from side

120-120 + <8 = 180-120

< 8 = 60

<1 and <5 are corresponding angles

Corresponding angles occupy the same relative position at each intersection.
