Answer:
m∠GHE = 117°
Explanation:
In the case of an equilateral trapezoid, the angles on the bases (parallel sides) are the same (congruent):
m∠GFE ≅ m∠HEF = 63° and m∠FGH ≅ m∠GHE = ?
Angles m∠FGH and m∠GFE are supplemental (comparative) angles and their sum is 180°
m∠FGH + m∠GFE = 180° => m∠FGH = 180° - m∠GFE = 180° - 63° = 117°
m∠FGH = 117°
As we know that:
m∠FGH ≅ m∠GHE = 117°
m∠GHE = 117°
