Question

in figure 4 ABCD is a parallelogram in which angle ADC = 60 degree and Angle ACB = 70 degree.
find the measures of angle DCB angle, C A B and angle angle DAC

Answer 1

Angle DCB=120°, B=60, C=50, A=120, DAC= 70(alternate interior angle), &ACD=50 (becz by angle sum property of triangle ADC, ANGLE C =DCA+ACB.. So DCB=70+50=120. ,
