Question

Whats the red angle?
i cant seem to understand anything

Answer 1

65°

Explanation:

Sum of interior angles of a triangle = 180°

⇒ m∠EAB = 180 - 90 - 70 = 20°

⇒ m∠DAG = 90 - 45 - 20 = 25°

⇒ m∠AGD = 180 - 90 - 25 = 65°

ΔADG ≅ ΔAFG

⇒ m∠AGD = m∠AGF = 65°

ΔABE ≅ ΔAFE

⇒ m∠AEB = m∠AEF = 70°
