Question 26953: Can someone help?
The length of the longest leg of a triangle is twice the length of the shortest leg. The remaining leg is 2 inches longer than the shortest leg. If the perimeter of the triangle is 26 inches, how long is each leg?

You can put this solution on YOUR website! Let's call the longest leg A and the shortest leg C, so the middle leg will be B.
Now, from the problem, we have:
A = 2C and:
B = C+2 and:
A + B + C = 26 inches. So, if we substitute 2C for A and C+2 for B, we can solve for C.
2C + C+2 + C = 26 Simplify.
4C + 2 = 26 Subtract 2 from both sides of the equation.
4C = 24 Divide both sides by 4.
C = 6 Now that we have C, we can find A and B.
A = 2C = 2(6) = 12
B = C+2 = 6+2 = 8
Answer:
The longest leg is 12 inches.
The shortest leg is 6 inches.
The remaining leg is 8 inches.
