Question

ABCD is a parallelogram and angle A= 60 degrees , find the remaining
angles.

Answer 1

In parallelogram opposite angles are equal.

Hence angle A = angle C = 60°.

Sum of adjacent angles = 180°

angle A + angle B = 180°

angle B = 180° - 80°
= 100°

Hence angle B = angle D = 100°.

Hope it's helpful to u.

Answer 2

heya!!

here is your solution -

A = 60°
So, C will also be 60° (opposite angles)

Now other angles =>

Sum of the angles in a parallelogram = 360°

> A+B+C+D =360°
> 60°+B+ 60°+D =360°
> 120°+B+D =360°

B + D =360° - 120°
B + D = 240°   ( angle B is equal to angle D )
B + B = 240°
2 B = 240°
B =240° / 2
B =120°

Hence, the other angles are, B = 120°, C = 60° and D = 120°

hope it helps!!
