Problema Solution
A wire attatched to the top of a pole reaches a stake in the ground 20 feet from the foot of the pole and makes an angle of 58 degrees with the ground. Find the length of the wire.
Answer provided by our tutors
cos x = adjacent / hypotenuse
*The hypotenuse is the length of the wire
cos 58 degrees = 20 / hypotenuse
hypotenuse = 20 / cos 58 degrees
hypotenuse = 38 ft (nearest foot)
