An h = 135-ft tower is located on the side of a mountain that is inclined 32° to the horizontal. A guy wire is to be attached to

Vikentia [17]

Answer:

171 foot

Step-by-step explanation:

We are given that

Height of tower=135 ft

AC=55 ft

Let x be the length of shortest length of wire.

The angle of inclination of mountain with horizontal = $32^{\circ}$

The angle between sides AB and BC= $90+32=122^{\circ}$

Exterior angle is equal to sum interior angles of a triangle on the opposite sides .

We have to find the value of x.

We know that law of cosine

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

Substitute the values in the given formula we get

$x=\sqrt{(135)^2+(55)^2-2(135)(55)cos 122}$

$x=170.64 ft$

Hence, the length of wire needed=171 foot

How to solve (x^(1/2))^4=36

harkovskaia [24]

Use the laws of exponents to simplify the expression, then take the square root.
x^2 = 36
x = √36
x = 6

_____
Note that the negative square root is not a solution if you require x^(1/2) be real. If that restriction is removed, then x = -6 is also a solution.
