Answer: 
Step-by-step explanation:
For this exercise you need to remember the following Trigonometric Identity:

You must observe the figure given in the exercise.
You can notice that the given triangle UVW is a Right triangle (because it has an angle that measures 90 degrees).
So, you can identify in the figure that:

Knowing these values, you can substitute them into
:

Now you must evaluate:

Finally, rounding to the nearest hundreth, you get:

Answer:
39
Step-by-step explanation:
4^3 equals 64, and 5^2 equals 25. 64 - 25 = 39.
Answer:
13 2/3
Step-by-step explanation:
divide each by three
5/3
12 5/3, or 13.66 repeating
Answer:
y = -6
Step-by-step explanation:
We are given;
1/3(2y+6)=y+4
We are required to solve for the value of X
First, we open the brackets;
(2/3)y + 2 = y + 4
Combining the like terms
(2/3)y - y = 4-2
Solving for y
(-1/3)y = 2
-y = 6
y = -6
Hence, the value of y is -6
The area would be 8 2/3* 5 3/4 which according to my calculator is 49 5/6
So the area is 49 5/6 ft^2.
Hope this helped!
