side is 10cm.
and unequal​

Answer 1

Answer

15 cm

Step-by-step explanation:

There are 3 sides in an isosceles triangle. Two of them are congruent or equal. The perimeter or sum of all side lengths in the shape is 40 cm. One side is 10 cm. That means the sum of the 2 other sides is 30 cm. Since both sides are equal, we have to divide 30 by 2 to get two equal parts. This is 15. 15 is the final answer.
