John is looking up at the top of the Empire State Building from 1 mi. away and measures the angle of elevation to be 11 degrees.

torisob [31]

Refer to the attached image.

Let the height of the Empire State Building = BC = 'x'

John is standing at distance from Empire State Building = AB = 1 mile

The angle of elevation = 11°

In triangle ABC,

Consider $\tan 11^{\circ}= \frac{Perpendicular}{Base}$

$\tan 11^{\circ}= \frac{BC}{AB}$

$\tan 11^{\circ}= \frac{x}{1}$

$0.194= \frac{x}{1}$

x = 0.194 mile

Since 1 mile =5280 feet

So, x = $0.194 \times 5280$

= 1024.32 feet.

So, the height of the Empire State Building is 1024.32 feet.

A marble is selected at random from a jar containing 4040 red marbles, 5050 yellow marbles, and 1010 green marbles. find the t

Elenna [48]

The answer will be total green plus total red divided by all existing marbles:
(1010 + 4040) / (1010 + 4040 + 5050) = 5050 / 10100 = 1/2 = 0.5

Answer: 0.5

A. Name 3 different angles which could have a reference angle of 20 degrees. How did you arrive at this answer?.

IgorC [24]

Answer:

Answer:a. Since 20° is in the first quadrant, the reference angle is 20° .

Answer:a. Since 20° is in the first quadrant, the reference angle is 20° .b. Reference Angle: the acute angle between the terminal arm/terminal side and the x-axis. The reference angle is always positive. In other words, the reference angle is an angle being sandwiched by the terminal side and the x-axis. It must be less than 90 degree, and always positive.

Answer:a. Since 20° is in the first quadrant, the reference angle is 20° .b. Reference Angle: the acute angle between the terminal arm/terminal side and the x-axis. The reference angle is always positive. In other words, the reference angle is an angle being sandwiched by the terminal side and the x-axis. It must be less than 90 degree, and always positive.c. The rays corresponding to supplementary angles intersect the unit circles in points having the same y-coordinate, so the two angles have the same sine (and opposite cosines).
