Question

There is a triangle. 2 sides are the same size. 5n-17 and 2n+1. and the smaller side is just n. I need the answers for the 2 sides and the smaller side and the perimeter

Answer 1

since the two sides are same,

5n - 17 = 2n + 1

or, 3n = 18

so, n= 6

first side: 6

second side: 5n-17= 5(6)-17 = 13

third side is 13

Perimeter: a+ b+ c

= 6+13+13
