The height of the pole happens to be the side (of this triangle) opposite the given 30 degree angle, and the hypotenuse (43 m) is given.  Thus, 

height of pole = opposite side = (43 m)*sin (30 deg)  = 21.5 m.

To find the length of the light pole you'll have to use the sine ratio.

sin 30 = x/43
43 (sin 30) = x
21.5 = x

Hope this helps :)

The lateral area of a cone is 19.2π in2. The radius is 2.4 in. Find the slant height.
Alexus [3.1K]

The slant height of a cone with lateral surface are of 19.2π inches squared and radius of 2.4 inches is 8 inches.

<h3>Lateral surface area of a cone</h3>

The formula for the lateral surface area of a cone is described as follows:

Lateral area = πrl

where

  • r = base radius
  • l = slant height

Therefore,

Lateral area = 19.2π inches²

r = 2.4 inches

Lateral area = π × 2.4 × l

19.2π = 2.4πl

divide both sides by 2.4π

l = 19.2π / 2.4π

l = 8 inches

What is the present value of $6,000 to be received at the end of each of eight periods, assuming the first payment occurs at the
Kipish [7]

Answer: Present value = $7200

Step-by-step explanation: Given Principal that is the original amount is $6000

Rate is 10% every fourth year

But the total period is eight.

So the interest would be paid 8/4 = 2 times.

Therefore,

Simple interest

= {principal * rate * no of times}/100

= {$6000*10*2}/100

Simple interest = $1200

Present value

= principal + Simple interest

= $6000 + $1200

= $7200.
