Answer:
angle 7= 66
Step-by-step explanation:
Angle 1 is equal to the 114 degrees. And angle 1 + angle 7 = 180. So it would be 114 + angle 7 = 180. So you do 180-114 = 66. So angle 7= 66.
The other way is that 114 + angle 6 = 180, so you do 180-114= 66.
And agle 6 is equal to angle 7, so that's another way you can know that angle 7= 66
