Answer:
Step-by-step explanation:
Use the Triangular Interior Angles Theorem to figure this out:
180° = [7x + 1]° + [6x - 6]° + 55°
180° = [−5 + 13x]° + 55°
180° = [50 + 13x]°
-50° - 50°
____________
You then plug this back into all three expressions to get 71° as the measure of ∠G and 54° as the measure of ∠T.
