Question

Find the m A)50 degrees B)60 degrees C)70 degrees D)80degrees

Answer 1

Answer:

Step-by-step explanation:

∠DEC + ∠EDC + ∠ECD = 180  {angle sum property of triangle}

45 + 65 + ∠ECD = 180

110 +∠ECD = 180

∠ECD = 180 - 110

∠ECD = 70°

AB // CD and AE transversal

∠BAC = ∠ECD    {Corresponding angles are equal}

∠BAC = 70°

Answer 2

Answer:

70

Step-by-step explanation:

65 and 45 make up 110, and triangles are composed up 180°. The missing angle thatll make it add up to 180 is 70
