Question

The first side of a triangle measures 4 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?
a. s - 4
b. s - 1
c. s + 3

Answer 1

Answer:

b . s-1

Step-by-step explanation:

let the length of second side be s..

then first side is s-4

and third side is (s-4)+3 = s-1

perimeter is s + (s-4) + (s-1) = 3s - 5 = 17

or s = 22/3
