What is the perimeter of a triangle with sides of lengths 5,8,& x? 13 + x
40 + x
40x
21

it should be a and d. lmk if i'm wrong xd

thats not a system of equations, that is a solution

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
