One of the equal sides of an isosceles triangle is 3 m less than twice its base. The perimeter is 44 m. Find the lengths of the sides.

1 answer

the angles sum to 180.
So, if the base is x, each of the other two sides is 2x-3.

SO, now you have to find x when

x + 2x-3 + 2x-3 = 44

Having found x, you can now determine the lengths of the sides.
