What is the measure of ∠7? 120° 90° 60° 180°

OpenStudy (anonymous):

OpenStudy (adryin):

60

OpenStudy (adryin):

2 is congruent to 6

OpenStudy (adryin):

120+x = 180

OpenStudy (adryin):

x= 60

OpenStudy (kayders1997):

Huh?

OpenStudy (kayders1997):

Wouldn't it be the angle 120?

OpenStudy (kayders1997):

Angle 6 and 2 are corresponding angles so they equal the same amount and than opposite angles 6 and 7 have the same angle measure so it should be 120 degrees

OpenStudy (kayders1997):

And plus you can tell that the angle is more than 90 because it's larger than a right angle

OpenStudy (adryin):

kayders is right my bad.

OpenStudy (adryin):

half a circle = 180 degrees

OpenStudy (adryin):

140+x = 180

OpenStudy (kayders1997):

Didn't you see my response before?

OpenStudy (adryin):

Ab = 40

OpenStudy (kayders1997):

Because half a circle is 180 degrees
