Answer:
Step-by-step explanation:
Use the cosine ratio, adjacent over hypotenuse. Plug in the values
cos70=x/25.5
Isolate x. Multiply both sides by 25.5
x=25.5*cos70
Enter the equation into a calculator
I don't know where you got those answers, but the actual equation that represents those points is: y = -1/2x + 11. None of those listed above are correct.
You have to subtract $2.50 and $5.05 then you divide that with 3 and you should get $0.85
Answer:
The answer would have to be B
