Iwo wires are attached to the top of a billboard. One is in front of the billboard, is 100 m long and nakes an angle of 45° to the ground. The second vire is attached to the exact same point on the billboard as the first, but it is at the back, nd makes an angle of 60° to the ground. To the nearest metre, determine the distance etween the two points where the two wires are attached to the ground.
