Answer:
19.10
Step-by-step explanation:
If im correct,
You subtract 10 and 5. Wich is 5. Then multiply that by 3.82.
38.4 is the area. it’s 8.5 ft long so you do 8.5x2 and you get 17, and then for 10.7 you do 10.7x2 and get 21.4, then you add 21.4 and 17 together.
In the second quadrant, both cos and tan are negative while only sin is positive.
To find tan, we will use the following property below:

Sec is the reciprocal of cos. If cos is a/b then sec is b/a. Since cos is 2/3 then sec is 3/2

Since tan is negative in the second quadrant. Hence,
