Question

10. Two equal sides of an isoscles triangle are each 2 em more than thrice the third side
the perimeter of triangle is 67 cm, find the lengths of its sides.​

Answer 1

Answer:

21 1st side 23 bot the last side as isosceles triangle has 2 sides equal

explanation

let take 1st side be x another 2 sides be x + 2

perimeter is 67

a.t.q

x+x+2+x+2 is equal to 67

3x + 4 is equal to 67

3xis equal to 67-4

x is equal to 21

both sides be 21 + 2 so both sides will be 23

Answer 2

Perimeter of Triangle = a + b + c

Let 3rd side = x

2nd side = 3x +2

1st side = 2 *(3x+2)

Then ,

A/Q,

x+ 3x +2 + 6x + 4  =  67

10x + 6 = 67

10x = 61

x = 6.1  => 3rd side

Sides

2nd side = 18.3 cm

1st side = 18.3 * 2 = 36.6 cm
