Question

ABCD is a rhombus such that ZACB = 40° find ZADC. ( 100°)​

Answer 1

Answer:

In a rhombus, diagonals bisect angles

so angle ACB = angle ACD = 40

so complete angle C = 80

but in a parallelogram adjacent angles sum is 180

so angle ADC + angle DCB = 180

angle ADC + 80 = 180

angle ADC = 100
