## Question

How do you find the radian measure of an angle?

## Answer

In order to find an angle, you can use a protractor. You can turn angles that are in degrees and turn degrees into radian by knowing the following formulas.

So if we have a measure of 20 degrees we can convert it by multiplying the degrees by the radian formula like the following:

If we had 10 radian, we would use the following formula.

Since

180∘=π radians,

if you want to convert x degrees to radians, then

x×π180 radians,

and if you want to convert x radians to degrees, then

x×180π degrees

I hope that this was helpful.
