Trigonometry
Arc Length and Radian Measure
Solve the following problem.
Convert 2π/4 radians to degrees.

radians is equal to 90°.

Step-by-step explanation:

Step 1:

If an angle is represented in radians, it will be of the form radians.

If an angle is represented in degrees, it will be of the form x°.  

To convert radians to degrees, we multiply the radian measure by .

For the conversion of radians to degrees,

the radians in degrees = (given value in radians)().

Step 2:

To convert  ,

So radians is equal to 90°.
