Since x represents one of the sides it cannot be negative;

Therefore x = 5;

So the triangle has sides of 5, 12, and 13.

Sorry ganesh, you are a lot faster than me! lol.

Since Pythogoras theorem is applicable, the triangle is right-angled. As (x+8) is the hypotenuse, x²+ (x+7)²= (x+8)² x²+x²+14x + 49 = x²+16x + 64 2x²+14x+49-x²-16x-64=0 x²-2x-15=0 x = [2 ± √(4+60)]/2 = (2 ± 8)/2 = 5 or -3. The lenghts of the sides are 5, 12 and 13, and these form a Pythogorean triple.

Please can you help me with this question?

I've got 3 lengths

x x+7 and x+8

x+8 is the hypotenuse.

I need to find the length of each side, I've tried but still can't figure it out, please help! Thanks in advance! ^_^
