Answer:

y·cos73°= x

Step-by-step explanation:

To find this, we can begin by looking at the steps to solve this problem. We know that this involved the 'opposite' and 'adjacent' sides, meaning we must use 'cos' in this instance.

We can set up an equation like this:

cos73°= \frac{x}{y}.

We can simply rearrange this to form a possible answer choice:

y·cos73°= x.

This is one of the answer choices! That is your final answer.

Colton has 888 comedy movies, 666 action movies, 555 fantasy movies, and 111 drama movie on his list of favorite movies.
eimsori [14]

Answer:

A. Comedy

Step-by-step explanation:

We are given that,

Movie type                        Number of movies

Comedy                                        8

Action                                           6

Fantasy                                         5

Drama                                            1

Then the total number of movies = 8+6+5+1 = 20

<h3><em>So, we will find the ratio of each type of movie out of total movies.</em></h3>

Ratio of comedy movies = \frac{8}{20}=\frac{2}{5}

Ratio of action movies = \frac{6}{20}=\frac{3}{10}

Ratio of fantasy movies = \frac{5}{20}=\frac{1}{4}

Ratio of drama movies = \frac{1}{20}

Since, we have,

<h3>Ratio of comedy movies = \frac{8}{20}=\frac{2}{5}</h3>

Thus, 'For every 5 movies on the list, there are 2 COMEDY movies'.

So, option A is correct.

From a point 80m from the base of a tower, the angle of elevation to the top of the tower is 28 degrees how tall is the tower
Nadusha1986 [10]

The height of the tower is 42.54 m.

Solution:

The reference image of the answer is attached below.

Given data:

BC = 80 m, ∠C = 28°

$\tan\theta = \frac{\text{Opposite}}{\text{Adjacent}}

$\tan28^\circ = \frac{AB}{BC}

$\tan28^\circ = \frac{h}{80}

$0.5317 = \frac{h}{80}

Multiply by 80 on both sides, we get

42.536 = h

Switch the sides.

h = 42.536

h = 42.54 m

The height of the tower is 42.54 m.
