Sales tax is 7.5%.how much did tammy’s lunch cost before tax if the tax on it was $0.72? define a variable and write an equation. solve the equation and check your solution

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

answer:

your answer is: c. 196 7/8 in^3.
