The trigonometric values for a right triangle can be obtained through the measurements of the different sides, 

this can be found in a triangle like this, 
then, identify the measurements in the given triangle 
then, 
 
 
        
             
        
        
        
He would have earned 17.75
Just subtract 6.75 from 24.50
24.50-6.75=17.75
        
             
        
        
        
i would just answer somewhere near the bottom but since your not allowed to do that your answer is (4)(-5)(3)...leeme know if i helped...also..lemme know if i didnt help...

Answer:
I believe it is 2(x-5)²−1
Step-by-step explanation:
The parentheses represent the horizontal shift. (X-__) is a shift to the right. (X+__) is a shift to the left. The last number of the function is the vertical shift. A negative number is shifting down and a post number is shifting up.
So, if the graph shifts up three units, then you add 3 + -4 to get -1. And if the graph shifts right 2 units, then you subtract 2 from -3 to get -5.
