Question 148741: Hypotenuse of right angle is 60 cm. if the leg is five cm longer than the other leg, what is lenght of the legs.
I know the formula is c^2= a^2 + b^2
60^2= x^2 + (x+5)^2
60^2= x^2 + x^2 +10x +25
3600= 2x^2 + 10x + 25
Now what are we solving 4 x?

Question 148953: Greg is making a bike ramp in the shape of a right triangle. The base of the ramp is 4 inches more than twice its height, and the length of the incline is 4 inches less than three times its height. How high is the ramp? My question is in setting up the problem-do I have 2x+4 and 3x-4 for the formula c2=a2 + b2?

Question 150498: Are there any other shapes that can be formed of the side of the side of the triangle besides squares that can complete the formula for example a hexagon? I have use a circle and that works if you use the length of the sides as the diameters. I think this is because of the square in the r2 is essentially the same as Pythagoras.

Question 171507: Given the triange with a hypotenuse = 20 , and one leg = X + 8 , and the other leg = X
Approximate to the nearest foot how many feet of walking distance a person saves by cutting across the lawn instead of walking on the side walk.
I know you use pythagorean theorem to get {2x^2 + 16x -336 = 0}
then simplify and get 2(x^2 + 8x - 168) = 0
After this you use quadratic equation and get -4 +- ^736 over 1
I dont know how to get the whole number after this
Thanks
