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°.
Leni [432]

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:

c=\sqrt{a^2+b^2-2ab cos\alpha}

AC=\sqrt{(650)^2+(180)^2-2\times 650\times 180\times cos 80^{\circ}}

c=643.64 ft

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=\frac{650}{2}=325 ft

Pythagorous theorem :(Hypotensuse)^2=(perpendicular\;side)^2+(base)^2

Substitute the values

(AC)^2=(AB)^2+(BC)^2

(AC)=\sqrt{(325)^2+(180)^2}

AC=371.52 ft

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.
