: A manufacturer recommends attaching a guy wire to its 40-ft antenna at a 45 angle. If the antenna is installed on a flat surface, how long must the guy wire be (to the nearest foot) if it is attached to the antenna 4 ft from the top. This question is from textbook

If the antenna is vertical then the angle the wire makes at the top is the same
as the angle on the ground since 45 + 45 + 90 = 180
The sides are in the ratio 1, 1, sqrt%282%29
In this case, 36, 36, 50.912
The wire must be 51 ft long to the nearest foot
