Question

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

Answer 1

Answer:

50⁰

Explanation:

in parallelogram adjacent angles are linear pair

60+70+ x = 180

x= 180- 130

x =50

Answer 2

Answer:

Opposite angles of parallelogram are equal.

∠DAB=∠BCD=75 '

and ∠DBC=60'

∠BDC+∠DBC+∠BCD=180'

∠BDC=180'

−∠DBC−∠BCD=180 '

−75'

−60'

=45'
