Angle G is congruent to only two angles in this problem: angle I and angle E.
Angle G is congruent to Angle I because they are vertical angles.
Angle G is congruent to Angle E because they are alternate interior angles.
Hope this helps!
The answer would be 243 because 9 x 20 is 180 and 9 x 7 is 63 so 180+63 is 243
