Question

5. Find the measure of the sides if parallel sides of a
parallelogram are 5x + 7 and 3x + 9.​

Answer 1

Answer:

here is your answers

Step-by-step explanation:

5x+7and 3x+9.

5x+7+3x+9=180

(because the sum of parallel sides of a parallelogram is 180 degree)

8x+16=180

8x=180-16

8x=164

x=164/8

x=20.5

measure of 1st side

=5x + 7

=5(20.5)+7

=109.5

measure of 2nd side

=3x + 9

=3(20.5)+9

=111.5
