The perimeter of a triangle is 45 centimeters. The longest side is 5 centimeter(s) less than the sum of the other two sides. Twice the shortest side is 4 centimeters less than the longest side.
Find the lengths of each side of the triangle.
The length from the shortest to longest are_, _, and _ centimeters?

Best ResponseYou've already chosen the best response.0The information you're given allows you to set up three equations in three unknowns. Name the sides as: l = longest s = shortest a = remaining side The perimeter is 45, which is the sum of the lengths of the sides, so\[l+s+a=45\]is one equation. You're told that the longest side is 5 LESS than the SUM of the other two sides, so\[l=a+s5\]and finally, TWICE the shortest side equals 4 LESS than the longest, namely,\[2s=l4\]

Best ResponseYou've already chosen the best response.0You have three linear equations in three unknowns, so you can solve the system exactly.

Best ResponseYou've already chosen the best response.0Well, you have to do some substituting. Take any one of you equations to begin with. Use the second to plug into the third to eliminate for l. So,\[2s=(a+s5)4=a+s9 \rightarrow a=s+9\]

Best ResponseYou've already chosen the best response.0If you sub. the equation for l (second one) into the first, you should get\[(a+s5)+s+a=45 \rightarrow s+a=20\]

Best ResponseYou've already chosen the best response.0If you sub the same second equation for l into the third, you get\[2s=(a+s5)4 \rightarrow as=9\] (forget the equation I solved at the very beginning, I stuffed the sign).

Best ResponseYou've already chosen the best response.0You now have \[a+s=20\]and\[as=9\]

anonymous

Best ResponseYou've already chosen the best response.0If a=9+s from the second equation here, then putting it into the first, you get\[(9+s)+s=20 \rightarrow 2s=11 \rightarrow s=\frac{11}{2}\]

Best ResponseYou've already chosen the best response.0Which means, from any of the two equations involving a and s above, for a,\[a=9+s=9+\frac{11}{2}=\frac{29}{2}\]

anonymous

Best ResponseYou've already chosen the best response.0Now from your perimeter equation, you can solve for l:\[l=45as=45\frac{29}{2}\frac{11}{2}=25\]
