Question

perimeter of a triangle is 49 ft. One side is 7ft shorter than the second side. Third side is 4 feet shorter than the second side. Find the length of each side.​

Answer 1

Second side = x feet

First side = x - 2 feet

Third side = x - 4 feet

Perimeter is 15 feet

15 = x + x - 2 + x - 4

Solve for x and then plug your x-value back into the three sides given above
