Question

Two adjacent sides of a parallelogram are in the ratio 5:7 of the perimeter of the parallelogram is 72cm find the length of its side if one of the angle is 52 degree find the other three angles

Answer 1

Step-by-step explanation:

Let the adjacent side be 5x and 7x respectively.

We know that opposite sides of parallelogram are equal and opposite

So, 5x+7x+5x+7x=24x [Perimeter]

Given, 24x=72

x=3

Hence length of sides of parallelogram are 5×3 and 7×3 or 15 cm and 21 cm.
