Question

Two opposite anglrs ofa parallelligram are (5x-21) and (x+75). Find the measure of each angle of the parallelligram
​

Answer 1

Step-by-step explanation:

5x-21=x+75

5x-x=75+21

4x=96

x=24

Answer 2

in a parallelogram opposite angles are equal so ,

5x-21 = x+75 so , x = 24

then one pair of angles = 5×24 - 21 = 99

the other pair of angles is give by,

( 360 - 2×99)/2 = 81

therefore angles of parallelogram are 99 , 89 , 99 , 89 in degree
