Question

in the adjoining figure 12.24 ABCD is a rhombus and angle ACB equal to 45 degree angle find angle ADC​

Answer 1

Answer:

angle ACB =angle CAD [alt.int.angle]

AD = DC (sides of rhombus are equal)

ang.DAC = ang.ACD (ang. oppto eq.sides are eq.)

ang.ADC +ang.ACD +ang.ADC=180

ang.ADC = 90
