Answer:
You would subtract 180 from 102 and the same for angle 146
180-102
=78
180-146
=36
Then you would subtract these two angles from 180 because th angles listed above are the bottom angles
36+78
=114
180-114
=66
The green angle is 66 degrees
the measure of the green angle is 68. The explanation? 180-146=34 and 180-102=78. You now have the two angles you need, so simply do 180-34-78=68.
