Answer 2

a triangle has three sides

1. First side of triangle = x
2. Second side of triange = x +10
3. Third side of triangle = x + 10 + 10

perimeter of tirange is sum of all side

perimeter = 5x + 4x = 9x

• x + x + 10 + x + 10 + 10
• 3x + 30 = 9x
• 30 = 9x - 3 = 6x
• x = 30/6 = 5

First side = 5

Second side = 5 + 10 = 15

Third side = 5 + 10 + 10 = 25

Perimeter of Triangle = 25 + 15 + 5 = 45 cm.
