David is standing 500 feet away from the base of the cell tower the angle of elevation from his eyes to the top of the tower 78° is David eyes are 6 feet above the ground how tall is the tower

the tower is 2358.3 feet tall

Step-by-step explanation:

A right angle triangle is formed between the tower, the angle of elevation of David's eyes and his distance from the tower.

Since the angle of elevation from his eyes to the top of the tower 78°, his distance from the tower represents the adjacent side of the right and triangle and the height of the tower represents the opposite side of the right angle triangle.

To determine the height of the tower,h we would apply

the tangent trigonometric ratio.

Tan θ, = opposite side/adjacent side. Therefore,

Tan 78 = h/500

h = 500tan78 = 500 × 4.7046

h = 2352.3

The total height of the tower would be 2352.3 + 6 = 2358.3 feet

the clues that signal the reader should change tone are the punctuation marks, the grammatical signs. for example, the quotation marks at the beginning of something someone else said literally or the exclamation marks.

the tone of the first line of dialogue until "gettysburg" is a kind tone, a tone of advise. the narrator is trying to the other person in doing something he or she obviously is finding hard to do by giving a piece of advise and bringing up a memory of a successful similar case.

the clue that the reader understand how to read the word "bang" is the exclamation mark. it gives the word a surprise tone, a strong accent.

the best tone for reading the word "bang" is an exciting tone, a surprise one, even a loud one.

the words that should be read with a formal tone are the ones that give factual information. the sentence: mister lincoln couldn't think of anything to say at the gettysburg" gives information about an event and it needs to be read formally, also, when the narrator wants to transmit calmness, a formal and slow tone is needed, because people also transmit messages with the vibrations of our voices and tones.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
