Step-by-step explanation:

Hey bro, hero you go:

In a parallelogram Angle A + Angle C = 180

[Co - interior angles]

100 + C = 180°

B = 80°

Since, opposite angles of a parallelogram are equal

Angle C = D = 80°

Stay safe and have a great day.

Thanks for 50 points.

Correct Question

parallelogram abcd , angle a + angle b + angle c is equal 100 degree, so d is equal to ?

Given

ABC = 100 degree

We find

Value of angle d

Formula used

A + B + C + D = 180 degree

According to the question

 = abcd\:  = {180} \degree \\  \\  = abc \:  + d = {180} \degree \\  \\  = 100\degree + d = {180} \degree \\  \\  = d = {180} \degree - 100\degree \\  \\  = d = 80\degree

So Angle D is 80 degree.
