A 500-foot cable is attached to the top of a tower and is stretched tight to a point that is 350 feet away from the base of the
Fantom [35]

The angle of depression the cable forms is the arctan of the ratio of the

horizontal distance to the height of the tower which is approximately 35°.

Response:

B. 35°

<h3>Which method can be used to find the angle of depression?</h3>

Given:

Height of the tower = 500-feet

Horizontal distance from the (other)  point of attachment of the cable to

the base of the tower = 350-feet.

Required:

The angle of depression formed by the cable.

Solution:

The angle of depression is the angle, θ, the cable forms with the tower

from the top of the tower.

By trigonometric ratios, therefore;

tan(\theta) = \mathbf{\dfrac{Horizontal \ distance \ of \ cable \ from \ tower}{Height\ of \ tower}}

Which gives;

tan(\theta) = \dfrac{350}{500} = \dfrac{7}{10}

  • Angle \ of \ depression, \ \theta = \mathbf{ arctan \left(\dfrac{7}{10} \right) }\approx35^{\circ}

The best correct option is; <u>B. 35°</u>

V/8=2<br> Find the value of V?
natita [175]

Answer:

16

Step-by-step explanation:

Basic Algebra, isolate V.

Do the opposite equation to get V on its own.

Because it is V/8, multiply both sides by 8 to get 8 on its own (if you wanted to move v over you would divide)

\frac{v}{8} =2

v =2*8

v =16

Is pi a irrational number or a rational number?
Tanya [424]
Is an irrational number because rational numbers are able to be expressed as a quotient of two integers. 22/7 s not an accurate but an approximate expression of pi so it doesn't work. Also, pi is a decimal that goes on without end but doesn't repeat so it is irrational.
