x=-5
Step-by-step explanation:

The answer is for 1st question is “10.4” and for the second question “non of these choices are correct”.
Explanation:
For the 1st question:
tan = opposite / adjacent
tan 30 = x / 18
18 tan 30 = x
x = 10.4
For the 2nd question,

Answer: X=4
Step-by-step explanation: distribute by subtracting 25 from both sides giving you 32=8X and then divide by 8 on both sides to get 4. Hope that helps
Answer:
the transformed function will be: 
Step-by-step explanation:
We need to transform
into g(x) using following translations
1) reflection in the x-axis
The reflection across x-axis will be:

2) Horizontal shrink by a factor of 1/3
The horizontal shrink by a factor of 1/3 will make the function g(x)

3) Vertical translation up 2 units
The vertical translation up 2 units will make the function g(x)

So, the transformed function will be:
