Question

The base of an isosceles triangle is 2cm. The perimeter of the triangle is 10cm. find the length of the equal sides

Answer 1

4 cm

Explanation:

An isosceles triangle has equal sides. That means that if each is is equal to unknown value "s", then the equation would be 2s (two times s) +2=10

Then, reduce both sides by two. 2s+2-2=10-2, ----> 2s=8, divide both sides by 2, s=4
