Question

In the figure, ABCD is a rhombus and ZACB = 45°.Find ZADC.​

Answer 1

Answer:

ADC = 90 degree

Step-by-step explanation:

Given that,

ACB = 45 °

DAC = ACB = 45° ( A. I. A)

Thus it is a rhombus,

AD = DC

DAC = DCA = 45°

In triangle ADC,

DAC + ACD + ADC = 180°

45° + 45° + ADC = 180°

90° + ADC = 180°

ADC = 180°- 90°

= 90°

( sorry I haven't written angle)
