Question

In a parallelogram, an angle measures 80°. What is the value of its adjacent angle

Answer 1

Answer:

100 degrees

Step-by-step explanation:

In a parallelogram,sum of interior angles equals 360 and opposite angles are equal. So

let's consider the different angles as x and y

where x is given as 80

now

2x+2y=360

2(80)+2y=360

2y=360-160

2y=200

y=100

Answer 2

Answer:

100 degree

Step-by-step explanation:

in a parallelogram ABCD

angle A + angle D = 180

let angle A = 80 (given)

that's why angle D= 180-80

= 100 degree
