An equation that expresses a relationship between two or more variables, such as Upper H equals nine tenths left parenthesis 220 minus a right parenthesis , is called Formula.

A formula is an equation that expresses a relationship between two or more variables.

The process of finding formulas to describe real-world phenomena is called mathematical modeling.

Such equations, together with the meaning assigned to the variables, are called mathematical models.

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.
