The height of a radio tower is 650 feet, and the ground on one side of the tower slopes upward at an angle of 10°.
(a) how long should a guy wire be if it is to connect to the top of the tower and be secured at a point on the sloped side 180 feet from the base of the tower?
(b) how long should a second guy wire be if it is to connect to the middle of the tower and be secured at a point 180 feet from the base on the flat side?

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.

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

the number 100 represents the number of trials in the experiment.

49/100 represents the experimental probability of the coin landing heads up.
