If two sides of a triangle are 5 and 8. The possible third side is

12

Step-by-step explanation:

Since 5+8=13, it has to be less than 13. The greatest possible perimeter is 25.

This means that 12 could be a possible side length for the third side.

it would be a on edgenuit y

the diagram below is your final answer

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
