A 125-ft tower is located on the side of a mountain that is inclined 32° to the horizontal.
A guy wire is to be attached to the top of the tower and anchored at a point 55 ft
downhill from the base of the tower.
Find the shortest length of the wire needed.Code:o A * | * | * |125 * | x * 122° o B * *58°| * * | * * 55 | * * 32° | C o - - - - - - - - - o D
