One side of triangle is 6 more than 2 times the shortest side. The third side is 20 feet more than the shortest side. The perimeter is 90 . Find all three sides.

Question

im trying to figure the formula thank you

Answer 1

s = shortest side

2s + 6 = "one side"

s + 20 = 3rd side

s + 2s + 6 + s + 20 = 90

4s + 26 = 90

4s = 64

s = 16

2(16) + 6 = 32 + 6 = 38

16 + 20 = 36
