I need clear steps to solve this. I am struggling with this part.

In order to find the average of all the costs, first you need to add up all of the expenditures from each month. (ex. 1,084.45+886.40+968.45+1,117.60+995.80+1,379.86) After you find the solution from adding those numbers together, divide the solution by the amount of costs there are in order to find the average. Since it was for 6 months, get the total from the addition problem and divide it by 6 and that will be your answer.

Find the measure of . (to the nearest tenth) PLEASE I NEED HELP :((

Kobotan [32]

Answer:

Step-by-step explanation:

This is classic right triangle trig. First decide how each side is related to the angle theta. The side 7.7 is opposite the angle theta, while the side 14 is adjacent. That is the tangent ratio by definition. Setting up the tan ratio:

$tan\theta=\frac{7.7}{14}$

To find a missing angle on your calculator, hit the 2nd button, then the tan button and enter in 7.7/14 and hit enter. You should get an angle measure of 28.8°

If you did not get 28.8 then you are probably in radians. Check it in the "mode" of your calculator.
