Question

pls help me find angle ace

Answer 1

Answer:

ACE = 20°

Step-by-step explanation:

BAC = 70°

SO , DAC=70° ( ALTERNATE ANGLE )

ECD = 180°-130° = 50° (CO INTERIOR ANGLE)

SO , ACE = DAC-ECD= 70°-50° = 20°

Hope this helps you .

Answer 2

Answer:

Given,  EF || CD

∠EFC + ∠ECD = 180°       (co-interior angles are supplementary)

∠ECD =180° - 130° = 50°

Given,  BA || CD

∠BAC = ∠ACD = 70°         (alternative angles)

∠ACE + ∠ECD = 70°

∠ACE = 70° - 50° = 20°
