Given :-

Unequal side of isosceles triangle is 10 cm.

Perimeter of triangle = 36 cm

====================

To Find :-

Measures of equal sides

===================

Solution :-

We know that,

Perimeter of isosceles triangle = Side + Side

Then let the equal side be x.

So,

Perimeter = 10 + 2x

→ 36 - 10 = 2x

→ 26 = 2x

→ 26/2 = x

→ 13 = x

Hence, measure of equal side is 13 cm.
