Help me PLEASE I'm confused!!!
The hypotenuse of a right triangle is 1cm longer than the longer leg. The shorter leg is 7cm shorter than the longer leg. Find the length of the longer leg of the right triangle.Label each side of the triangle. Then substitute into Pythagorean Theorem.

Best ResponseYou've already chosen the best response.2Shorter leg = x longer leg = x+7 hypotenuse = x+7+1 = x+8 Do you know how to proceed now ?

Best ResponseYou've already chosen the best response.1I'm guessing that x is the length of the longer leg, and that this can be written as: \[X^2+ (X7)^2 = X+1 \] Then, you can solve from there by expanding brackets and you get a quadratic equation: \[x^2 8x+48=0\]

Best ResponseYou've already chosen the best response.2Almost Correct , but x^2 + (x+7)^2 = (x+8)^2 Apply Pythagoras theorem!

Best ResponseYou've already chosen the best response.1Wait no.. my answer makes sense. Doesnt it? \[x^2+(x−7)^2=(x+1)^2 \] \[= x^2+x^27x+49=x^2 + x+1 \] \[x^28x+48=0 \]

Best ResponseYou've already chosen the best response.2: , ofcourse it does makes sense. But here, your hypotenuse isn't (x+1) , it is x+8 ..

Best ResponseYou've already chosen the best response.1Im taking x as the longer leg, not the shorter one

Best ResponseYou've already chosen the best response.2Okay, then the longer leg would be x , shorter length would be x7, and hyp would be x+1 .. Well done buddy :D , you were absolutely correct :D
