Answer: 77
================================================
Explanation:
The triangles are congruent by the HL Theorem.
As such, the corresponding pieces angles EGH and EGF are congruent
angle EGH = angle EGF
7u-70 = 2u+35
7u-2u = 35+70
5u = 105
u = 105/5
u = 21
This leads to
- angle EGH = 7u-70 = 7*21-70 = 147-70 = 77
- angle EGF = 2u+35 = 2*21+35 = 42+35 = 77
Both angles mentioned are 77 degrees each to help confirm the answer.
