Answer:
7= 137
6= 43
8=43
Step-by-step explanation:
well 7 would be the same angle as 137
and 6 and 8 are the same angle
so u already know that
now to find 6 0r 8 u just need to subtract 137 from 180 to get
8= 43
see explanation
∠7 = 137° ( vertically opposite angle )
∠8 = 180° - ∠7 = 180° - 137° = 43° ( straight angle )
∠6 = ∠8 = 43° ( vertically opposite angles )
