Answer 1

11 is your answer.

dear.

Answer 2

Hola!

Here's your answer

Let the two equal sides of an isosceles triangle be 2x

thus,

Perimeter of triangle = Sum of all sides.

so,


Here perimeter is 30cm

thus,


30 = 2x + 8

30 - 8 = 2x

22 = 2x

x = 22/2 => 11


thus,

Equal sides = 11cm



Hope it helps!
