Asked by Jhun Sanchez
A wall 10 feet high is 8 feet away from a house. Find the length of the shortest ladder that will reach the house when one end rests on the ground outside the wall.
So in here. I did the similar triangle property. so i got y=10(x+8)/x . And i substituted it in the PYTHAGOREAN Theorem.
z^2= (the equation y above)^2 + (8+x)^2. Please help, i don't know what to do from here.
