The base of an isosceles triangle is 7 cm longer than the legs. find the legs if the perimeter of the triangle is 43 cm.

(20 points and free brainiest )

An isosceles triangle has two congruent sides. We can give variables for each value. Let one congruent side length be x. Let the base equal x+7. Now, we write an equation.
x+x+x+7=43
3x+7=43
3x+7-7=43-7
3x=36
=
x=12
One leg is 12 cm. Combined, they are 24 cm.
Hope that helped you!
