If two sides are equal and the third is 4ft longer than the others, then the triangle is classified as isosceles. Written as an equation, it is 2x+(x+4)=49 with x being the length of one of the equal sides. Subtract 4 from bother sides to end up with 3x=45. This took the 4 extra feet away from the anomalous side. Now you have to divide three from both sides to get x=15. Now you can input x back into the original equation.2(15)+(15+4)=49. Separate the equation to be 15+15+19=49. This gives you each side of the triangle. 15 and 15 are the length in feet of the two equal sides, and 19 is the length of the longer, anomalous side.
