5 is not a function because if you draw a vertical line then it touches twice which is not a function
6 is a function
7 is not a function because there are 2 of the same inputs
8 is a function because it passes the vertical line test
9 is not a function

Answer:
The value of x = 13.5.
Step-by-step explanation:
<u>In this question x is missing.</u>
<u>So, the question would be:</u>
<u>tan 34° = x/20.</u>
Now, to find the value of
:


Multiplying both sides by 20 we get:

On simplifying both sides we get:

So, to get the value of
to nearest tenth is 13.5. As we see in hundredth place it is 9 and 4 in tenth place, so after rounding to tenth place 4 will change to 5 so the value is 13.5.
Therefore, the value of x = 13.5.
900=(1/2)*b*10*15
1800=150b
b=12
I hope you can figure out FC with this info.
