Question

One side of a parallelogram is 6cm one angle is 150degree if its area is 26 cm^2 find the other side.

Answer 1

Given : One side of a parallelogram is 6cm one angle is 150degree

its area is 26 cm^2

To find : the other side.

Solution:

area of parallelogram = absinα

a , b are the side length

α is the angle

=> 6 * b * sin *150°  = 26

=> 6 * b * 1/2 = 26

=> b = 26/3

Hence other side is 26/3 cm

Answer 2

Let a,b be the sides .

Area of Parallelogram = ab sinα

⇒ 6 * b * sin150 = 26

⇒ 6b * ½ = 26

⇒ b = 26/3 cm.

The other side is 26/3 cm
