In the figure below, BCA ~ STR. Find cos C, sin C, and tan C. Round your answers to the nearest hundredth.
arsen [322]

Answer:

\sin C\approx0.85\\\\\cos C \approx0.52\\\\\tan C\approx1.63

Step-by-step explanation:

According to the trigonometric ratios in aright triangle :

\sin x =\dfrac{\text{Side opposite to x}}{\text{Hypotenuse}}\\\\\cos x =\dfrac{\text{Side adjacent to x}}{\text{Hypotenuse}}\\\\\tan x=\dfrac{\sin x}{\cos x}

Given:  ΔBCA ~ ΔSTR

Since , corresponding angles of two similar triangles are equal.

So, ∠C = ∠T                            ...(i)    [Middle letter]

In triangle STR

\sin T=\dfrac{\text{Side opposite to T}}{\text{Hypotenuse}}\\\\=\dfrac{26.4}{30.9}\approx0.85\\\\\cos x =\dfrac{\text{Side adjacent to T}}{\text{Hypotenuse}}\\\\=\dfrac{16.2}{30.9}\approx0.52\\\\\tan T=\dfrac{\sin T}{\cos T}\\\\=\dfrac{0.85}{0.52}\approx1.63  ...(ii)

From (i) and (ii), we have

\sin C\approx0.85\\\\\cos C \approx0.52\\\\\tan C\approx1.63

ANSWER THIS AND GET A BRAINIEST . thank youu - 10 points
crimeas [40]

Answer:

18; 1h30m; 15

Step-by-step explanation:

<u>Part A:</u>

James traveled 45km, you can tell because that is where he stops.

It took him from 2pm to 4:30pm.

You can find this info on the x axis.

That means 45km took him 2.5 hours.

45/2.5=18

James travels 18km per hour.

<u>Part B:</u>

The stop is indicated by the flat part in the graph. This is because when he stops, the distance he is away from home is not changing.

His stop is from 4:30pm to 5pm.

This means that his stop is 1 hour and 30 minutes.

<u>Part C:</u>

James had to travel 45km to get back home. (45-0)

It took him from 5pm to 8pm.

This means that on his journey back, 45km took him 3 hours.

45/3=15

James travels 15km per hour.

Which of the following expressions represent 15% tip on a $20 meal? Which represents the total bill? **Select all that apply**.
kifflom [539]

Answer:

15/100 * 20, because the meal is 20 dollars and to find the percent of something you divide it with 100 so you will divide 15 with 100 and you’ll get 0.15. Then you will times it with the amount the meal cost because thats the charge. So 0.15•20 and you’ll get $3. A 15% tip for a $20 meal is $3.

21.4÷4.75

  • First- you have to move the decimal placement two times to the right
  • Second- you have to put the number 21.4 under the dividing box
  • Third- put the number 4.75 out to the left of the decimal box
  • Fourth- when that's all completed you have to multiply the 475. until you get clos to the number 2140.
  • Fifth- once done you have to subtract the multiplied number that you get you then subtract it from 2140
  • Sixth- you keep on doing the fifth step until you get a reasonable answer
  • Seventh- you write the answer down
  • Eighth- there is no eighth step so you can stop reading this answer
