A 125ft diagonal brace on a bridge connects a support of the center of the bridge to a side support on the bridge. The horizontal distance that it spans is 25 ft longer than the height that it reaches on the side of the bridge. Find the horizontal and vertical distances spanned by this brace.

125^2=height^2 + horiz^2
125^2=height^2+ (height25)^2
solve for height first.
