SOLUTION:
Step 1 :
Set up the right triangle with the following:
side a = x
side b = 13 + 3x
side c = 14 + 3x
Using pythagorean theorem :
Step 2 :
Expand this equation by using foil to get:
Simplifying this equation will give you:
Step 3 :
Factor this to get:
(x-9)(x +3) = 0
Solving this will give you x = 9 or x = -3.
The side length cannot be negative so discard the -3.
Step 4 :
Your side lengths will be:
CONCLUSION:
The side lengths of the triangle are:
9 m , 40 m and 41 m
