Question

The unequal side in an isosceles ABC measure 10cm if the perimeter of ABC is 36cm find The measure of its equal sides
​

Answer 1

Answer:

a = 13cm

Step-by-step explanation:

Let the equal side be a

Therefore,

Perimeter of isosceles triangle = 10 + a + a

=> 36 = 10 + 2a

=> a = 13cm

Answer 2

Answer:

Step-by-step explanation:

Let, ABC be an isosceles triangle. And AB be the unequal side.So, AC and BC are the equal sides.The equal side be x i.e AC=BC=x

Given,

The unequal side = 10cm

Perimeter = 36cm

AB+BC+AC=36

AB+x+x=36

10+2x=36

2x=36-10

2x=26

x=13
