Question

In the adjoining Figure,ABCD is a parallelogram. If angle DAB=85°and angle DBC=60°,then calculate:
1) angle CDB
2) angle ABD​

Answer 1

Answer:

1/2 of an answer is zero answer.

Step-by-step explanation:

Answer 2

Step-by-step explanation:

angle C = 85 coz opposite angle of a parallelogram r equal

in triangle DCB

|_D = ANGLE C +1/2 D +1/2 B =180

85+60+1/2D =180

145+1/2D=180

1/2D=180-145

1/2D= 35

ANGLE B = 2×1/2B

60×2= 120 COZ DIAGONAL BISECT THE ANGLE

ANGLE D =1/2D×2

=35×2

=70
