Question

The first side of a triangle measures 5 in. less than the second side, the third side is 3 in. more than the first side, and the perimeter is 17 in. How long is the third side? If s represents the length of the second side, which of the following represents the length of the third side? s - 5 s - 2 s + 3

Answer 1

s+3 will be the third side of the triangle

Answer 2

let 1st side be x

then 2nd side is x+2

3rd side is x+3

perimeter of triangle is a+b+c

putting value

x+x+5+x+3=17

=3x+8=17
3x=9

x= 3

putting value for 3rd side

x+3=3+3

= 6 ans
