Question

answer 38 fast...........

Answer 1

Answer:

AEF = 40

ACD = 60

AFG = 100

Step-by-step explanation:

DGF = AEF = 40 (corresponding angles of parallel lines)

BAC = ACD = 60 (alternate interior angles of parallel lines)

AFG = BAC + AEF = 60 + 40 = 100 (In a triangle, the sum of 2 adjacent interior angles is equal to the exterior opposite angle)

Hence proved.

Thank you.

Plzzz mark my answer as brainliest.

Answer 2

Answer:

AB║CD (GIVEN)

⇒∠AEF=∠DGH=40°   (CORRESPONDING ANGLES)

∠ACD=∠BAC=60° (ALTERNATE INTERIOR ANGLES)

In ΔAEF

∠AEF+∠EAF=∠AFG (EXTERIOR ANGLE PROPERTY)

⇒60°+40°=100°
