Question

In an isosceles triangle measure of two sides is 8 cm and perimeter is 30 cm find measure of third side.​

Answer 1

Answer:

let the third side be x

perimeter of isosceles triangle=2a+b

a=30

30=2*8+x

30=16+x

30-16=x

14=x=third side

Answer 2

Answer:

Third Side = 14cm

Given that ;

Measure of two sides = 8 cm

Perimeter of the Isosceles Triangle ( P ) = 30 cm

Perimeter ;

Sum of the three sides of the Isosceles Triangle

Let ;

The Third side = x cm

8 cm + 8 cm + x cm = 30

16 cm + x = 30

x = 30 - 16

x = 14 cm
