Question

Two opposite angles of a parallelogram are (5x-8) and (2x+82). find the measures of each angle of a parallelogram.​

Answer 1

Answer:

In a parrellelogrom the opposite Angel's are equal.

Therefore 5× - 8 =2×+82

5×-2×=82+8

3x=90

x=90/3

x = 30

5x-8 =5 (30) -8=150-8 =142

2x+82=2 (30)+ 82

=60 + 82 = 142

So,all the angles of a parallelogram are 142,38,142,
