Step-by-step explanation:
<u>Key skills needed: Equation, Division, Fractions</u>
1) Let's say the number is the variable "x".
2) So this means 9 times x = 800
9x = 800
3) Divide both sides by 9 and you will get x equal to 800/9. If you want this in mixed number form, it is --> 88 8/9

4cos(x)-2cos(x)=1+2cos(x)-2cos(x)
2cos(x)=1
cos(x)=1/2 (Positive cos are only in the first and 4th quadrants.)
x=π/3,
x=2π - π/3 = 5π/3
