Answer:
x = 88.2
Step-by-step explanation:
The angle at the top of the triangle = 90° - 10° = 80°
and the left side of the triangle is x ( opposite sides of a rectangle )
Using the tangent ratio in the right triangle
tan80° =  =
 = 
Multiply both sides by x
x × tan80° = 500 ( divide both sides by tan80° )
x =  ≈ 88.2
 ≈ 88.2
 
        
             
        
        
        
To find f(5), just look at the table and find the value for x that corresponds with f(5). In this case, this value is -1.
So, your answer is B. -1.
Hope this helps!

3/4 = 6/8 = 9/12
4/5 = 8/10 = 12/15
        
                    
             
        
        
        
Answer:
-3(4 - 6x)
-12 +18x
=18x - 12
Step-by-step explanation:
You multiple the negative 3 with positive 4 to get negative 12.
An you also multiple the negative 3 with negative 6x (a negative multiple a negative changes into positive) giving you 18x as your answer
