Question

in a quadrilateral ABCD , AB||CD, AD =CD and ∆BAC= 35 ° . find ∆ ADC

Answer 1

As ABllDC and AB=Dc therefore ABCD is a parallelogram angle A = 35 Therefore angle A + angle D = 180 ( Angles on the same side of the parallelogram is suplementry therefore angle D = 180 - 35 = 145

Answer 2

the correct answer is 145.as it is a parrelogram
