Trigonometric Ratios

In every right triangle (those who have an internal angle of 90°), the six trigonometric ratios are valid. They relate the other internal angles with the lengths of the triangle.

The skateboard, the wall, and the ground form a right triangle. We need to find the measure of the angle formed by the skateboard with the ground. Let's call it β. In a right triangle, the cosine of an angle is defined as

[tex]\displaystyle \cos\beta=\frac{\text{adjacent leg}}{\text{hypotenuse}}[/tex]

The adjacent leg of β is the side with length 8 in, and the hypotenuse is the length of the skateboard, 30 in, thus:

[tex]\displaystyle \cos\beta=\frac{8}{30}}=0.267[/tex]

Using a digital calculator we find:

[tex]\beta=\cos^{-1}(0.267)[/tex]

[tex]\beta=74.5^\circ[/tex]

Correct choice: C. 74.5

Answer:

she is expected to pay $288 in taxes

Step-by-step explanation:

She is expected to pay 12% of $2400, that is: 0.12 * 2400 = 288

So she is expected to pay $288 in taxes for such income.

Answer: The cost per bag is $27

Step-by-step explanation:

Divide 135 by 5 = 27

Unit ratio means that if you know the rate per unit, you can calculate the cost by multiplying the constant rate by the number of units. In this question, the rate is $27 and the unit is the bag.

The ratio looks like

1:27 as 2:54 as 3:81 as 4:108 as 5:135

They are all equivalent to 1/27

y = 27x is another way of writing an equation for this ratio.

Answer: The answer is $15.86

Step-by-step explanation: You would change 6.10 into a fraction, which is 61/10. Then you would mulitply that and that number as a decimal would be 15.86.

Answer:

$15.86

Step-by-step explanation:

You divide 6.10 by 5 and you get 1.22 then u multiply 1.22 by 3 and you get 3.66 and add 6.10 and 6.10 and 3.66 to get your answer.

Answer:

252.00

Step-by-step explanation:

Answer

For a discount of 40% The T.V. would be selling for $252

Step-by-step explanation:

40% Of $420 is $168, $420 - $168 is $252.

Answer:

0.5 because it has a total of 6 sides

Answer:

true for all x

Step-by-step explanation:

-2x + 12 = -2(x – 6)

Distribute

-2x+12 = -2x+12

Add 2x to each side

12 =12

Since this is always true, there are infinite solutions

x is all real numbers

Answer:

So since QRS is ~ another triangle, and they are not exactly similar, I assume that the problem wants you to compare QRS with another angle. QRS is closely congruent to UVW (assuming that you are comparing triangles not angles).

Step-by-step explanation:

All triangles have an angle total of 180 degrees. If you add those two angles together, they have the same sum, and the third anglecan be found by subtracting the total from 180. For example, 95+36 = 131. 180-131=49, which is the third angle for triangle QRS. You can do the same for UVW.

It is important to compare them in order. For instance, Triangle QRS would not be congruent to WVU since they are not in the same order. To compare them in the correct order, compare the angles. Q is about equal to U. R is about equal to V. S is about equal to W since they both have missing angles. Therefore, you can state that triangle QRS is about equal to UVW.

Answer:

  make use of the ways similarity can be shown

Step-by-step explanation:

Similarity of triangles can be shown two (2) ways:

__

In a worksheet like this, you may see several kinds of problems. The keys will be ...

__

When two angles are given, as here, at least one of them in one triangle must match one in the other triangle.

Here, neither of the measures 35 and 96 matches either of the measures 36 and 95. These triangles cannot be similar.

__

Further discussion on working these problems

If one of the numbers does match, then you need to find the third angle to see if it matches the remaining angle. If two numbers match, the triangles are similar by AA.

Even if you find all three angles match, you need to carefully check any similarity statement to make sure it lists the matching angles in the same order.

For example, suppose both sets of angles in these triangles were 94 and 37. ∆QRS lists these in the order 94° angle, 37° angle. Then the similarity statement would have to list the other triangle's vertices in the same order: ∆UVW. A typical problem might claim similarity to ∆VUW, just to see if you're paying attention to detail. That claim would be false.

__

For comparing side lengths, it can work well to compare them smallest-to-largest, or in some other order you find easy to remember.

Answer:

the lenght of the rectangle is five more than the width

Answer:

the answer should be 414

Answer:

414

or

103.5

Step-by-step explanation:

If these are singular values and for example 2 x 105 does not mean two datasets of 105 and 6 x 103 doesnt mean six datasets of 103, then your average would be as follows

((2 x 105) + (6*103)) ÷ 2

The two being how many sets of values you have

This would be solved as follows

((210) + (618)) ÷ 2 =

            (828) ÷ 2 = 414

So in this case it would be 414

However, if the two in 2 x 105 means two data sets of 105;

it would be the same steps of solving but with the ÷ 2 being replaced with ÷ 8 (2 + 6)

((2 x 105) + (6*103)) ÷ 8 =

        ((210) + (618)) ÷ 8 =

                    (828) ÷ 8 = 103.5

Hope this helps.

Answer:

$19.00

Step-by-step explanation:

This is the answer because:

1) In order to know what 5% of 20 is, you have to do 20 x 5/100 = 100/100

2) Next, 100/100 = 1

3) Finally, we have to do 20-1 which is 19

Therefore, the answer is $19.00

Answer:

6

Step-by-step explanation:

hi! absolute value is defined as the number of units away from zero on the number line. distance is always positive, so absolute value is always positive. therefore, the answer is 6 since you just take the negative sign away.

Answer:

four hundred thirty-two

Step-by-step explanation:

one third of 1296 is same as = ⅓ of 1296

⅓ of 1296 is same as = ⅓ × 1296

= ⅓ × 1296

= 1 × 1296 / 3

= 1296/3

Let us try to simplify this fraction . Both the numerator and the denominator is divisible by 3 .

Then ,

= 1296 ÷ 3 / 3 ÷ 3

= 432/1

= 432

Therefore , one third of 1296 is 432
