Question

The opposite sides of a parallelogram have measures (2x+10) cin and (x+15)

cm. What is the measure of the sides?​

Answer 1

The measure of the sides is 20 cm.

Explanation:

Opposite side of a parallelogram:

Opposite sides of a parallelogram are congruent, that is, they have the same measure.

Measures (2x+10) cm and (x+15) cm:

This means that:

`2x + 10 = x + 15`

`2x - x = 15 - 10`

`x = 5`

2x + 10 = 2*5 + 10 = 10 + 10 = 20

The measure of the sides is 20 cm.
