Find sin0, cos0, tan0

djverab [1.8K]

Answer:

sin(θ) = 12/13, cos(θ) = 5/13, tan(θ) = 12/5

Step-by-step explanation:

We need to find sine, cosine, and tangent of theta for this triangle.

First, define the different trigonometric functions:

- sine is opposite side to the angle divided by the hypotenuse (longest side not adjacent to the 90 degree angle)

- cosine is the adjacent side next to the angle divided by the hypotenuse

- tangent is the opposite side to the angle divided by the adjacent side

Now, look at theta (θ):

- the opposite side is marked 12

- the adjacent side is marked 5

- the hypotenuse is marked 13

So:

- sin(θ) = opposite / hypotenuse = 12/13

- cos(θ) = adjacent / hypotenuse = 5/13

- tan(θ) = opposite / adjacent = 12/5

Thus the answers are: sin(θ) = 12/13, cos(θ) = 5/13, tan(θ) = 12/5.

san4es73 [151]

Answer:

Michelle purchased 25 audio files in January. The percent increase is 60%

Solution:

Given Data:

Michelle purchases = 25 audio files in January

Again purchased = 40 audio files in February

We need to find the percent increase for the given data.

Step 1:

Use the formula for percent change ,

$=\frac{\text { amount of change }}{\text { original amount. }}$

Step 2:

First we find the amount of change from the question.

Amount of change = 40 – 25

By subtracting, we get 15.

Step 3:

substitute the values in formula we get,

Formula percent change = $\frac{15}{25}$ = 0.6

Percent = 0.6 $\times$ 100 = 60 %.

Result:

Michelle purchased 25 audio files in January. And In February she purchased 40 audio files. Hence the percent increase is 60%.
