Question

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

Answer 1

are you meant area of ADC??

Answer 2

Answer:

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 supplementary therefore angle D = 180 - 35 = 145
