Perimeter of parallelogram 140 cm if one side is longer than the other by 10cm, find the length of each of its parallel side

The length of each of its parallel side are 30 cm and 40 cm.

Step-by-step explanation:

Perimeter of a parallelogram = 2 (base+height)

⇒ 140 = 2(x+x+10)

⇒ 140 = 2(2x+10)

⇒ 140 = 4x+20

⇒ 4x = 120

⇒ x = 120/4

x = 30 cm

∴ The longer side = 30+10 = 40 cm

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.
