Question

in the quadrilateral ABCD AB=BC and AD=DC measure of angle BCD is​

Answer 1

Answer:

105 degrees

Step-by-step explanation:

angle BCA=angle BAC..therefore each angle is 72/2 that is 36.And in triangle ADC , angle DAC=angle DCA, that is 138/2 =69. so angle BCD=angle(BCA+DCA)=36+69=105..

Answer 2

so answer if this question is 20°
