Question 1116202: A cell phone tower is 250 feet high. How long should a guy wire be if it is to be attached to the tower 15 feet from the top and to make an angle of 25° with the ground? Round your answer to the nearest foot.How far from the center of the base of the tower is the guy wire attached to the ground. Round your answer to the nearest foot.What a second guy wire was attached to the same 250 feet tall cell phone tower exactly halfway up the tower. If the guy wire is to be attached to the ground 300 feet from the center of the base of the tower what angle does the guy wire make with the ground? Round your answer to the nearest tenth degree.

You can put this solution on YOUR website! A cell phone tower is 250 feet high.
How long should a guy wire be if it is to be attached to the tower 15 feet from the top and to make an angle of 25° with the ground?
:
Draw this out. The side opposite the angle is 250-15 = 235ft
The guy wire will be the hypotenuse (h) of the triangle made by the ground tie point and the height of the tower minus 15'.
Use the sine, side opposite/hypotenuse
sin(25) =
h =
h = 556 ft

:
How far from the center of the base of the tower is the guy wire attached to the ground.
Round your answer to the nearest foot.
:
Use the tangent of 25 degrees; side opposite/side adjacent (s)
tan(25) =
s =
s = 504 ft from the tower to the guy tie point

:
What a second guy wire was attached to the same 250 feet tall cell phone tower exactly halfway up the tower.
If the guy wire is to be attached to the ground 300 feet from the center of the base of the tower what angle does the guy wire make with the ground?
Round your answer to the nearest tenth degree.
:
Half way up a 250'tower: 250/2 = 125 ft
tan(A) =
A = 22.6 degrees
