Question

the perimeter of an isosceles triangle is 28cm•the base of this triangle is 8cm•what is the length of its equal sides​

Answer 1

Answer:

the length of the other sides are 10cm

Answer 2

Answer:

Let the length of equal sides of the triangle be x.

Perimeter of triangle = sum of all sides

                             28 = 8 + x + x

                       28 - 8 = 2x

                            20 = 2x

                             $\frac{20}{2}$ = x

                            10 = x

So the measure of equal sides of the triangle is 10cm.
