Question

in a parallelogram abcd, < D = 105 degree, determine the measures of angle A and angle b.

Answer 1

Given : angle D = 105° and a parallelogram ABCD.
To Prove : angle A = ? and angle B = ?
Proof : Angle A = Angle C ( opposite angles if parallelogram is equal )
and, angle B = angle D
therefore, angle B = 105°
Now, angle A + angle B = 180° ( adjacent angles )
angle A + 105° = 180°
angle A = 180° - 105°
angle A = 75°


.....hope you got your questions solution and the values of angles.
