Explain how trigonometry can be used to determine the height of a cell phone tower.

Mathematics

saul85 [17]2 years ago

Trigonometry can be used to determine the height of a cell phone tower by using SOH CAH TOA or the Pythagorean theorem. If you look at it as a right triangle you can figure out how tall the tower is. If an angle is given (not a 90°angle) and the value of a side you can figure out all of the sides on the theoretical right triangle. Including the height of the tower.

What is the probability that the first card is a kingking and the second card is a kingking if the sampling is done with​ replac
IRINA_888 [86]
You want to draw 2 kings from a 52 card deck. And you do it with replacement.
There are 4 kings in a standard deck. The probability of getting one of them is 
4/52 on the first draw.

For the second draw the probability is the same.
4/52

The probability for both happening is 
(4/52)*(4/52) = (1/13)*(1/13) = 1/169 = 0.001597

The aspect of geography that examines physical characteristics of the Earth is known as ______________.
antoniya [11.8K]
<span>The aspect of geography that examines physical characteristics of the Earth is known as physical geography. The correct option among all the options that are given in the question is the third option or option "C".

Number of people in the year 2010 = 308.7 million
Number of people in the year 2000 = 281.4 million
Number of people by which the population grew = (308.7 - 281.4) million
                                                                             = 27.3 million
Percentage of change in the population = (27.3/308.7) * 100
                                                                = 8.84 percent.

Hey! I'll provide you the answers!

First you want to simplify the equation using cross-multiplication.

15n = 2415

Finally, you would want to divide both sides by 15.

n = 161

In the diagram below, RA is parallel to ET, and RT is 21 units long. Find the length of ST
pav-90 [236]

Answer:

ST = 12 units

Step-by-step explanation:

As RA is parallel to ET, the angle in R is equal to the angle in T, and the angle in A is equal to the angle in E, so the triangle RAS is similar to the triangle SET.

If RT is 21 units, we have that RS + ST = 21 -> RS = 21 - ST

Using a rule of three with the sides of the triangle (as they are proportional), we have:

RS / ST = AR / ET

(21 - ST) / ST = 6 / 8

4 * (21 - ST) = 3*ST

84 - 4*ST = 3*ST

7*ST = 84

ST = 12 units
