Answer with Step-by-step explanation:
We are given that
Height of radio tower =650 ft
From figure
AB=650 ft
BC=180 ft
We have to find the AC.
Using cosine law:
Hence, a guy required 643.64 ft wire when it is to connect to the tower and be secured at a point on the sloped side 180 ft from the base of the tower.
b.In a right triangle ABC, AB=
Pythagorous theorem :
Substitute the values
Hence, the length of wire should be 371.52 ft when a second guy connect the middle of the tower and be secured at a point 180 ft from the base on the flat side by wire.
