Given the measure of an angle in degrees
To convert from the degree to radian, we will use the following formula:
[tex]\theta(rad)=\theta\degree *\frac{\pi}{180}[/tex]
Given the angle in degree = 225°
So, the measure of the angle in radian will be as follows:
[tex]225\degree *\frac{\pi}{180}=\frac{225}{180}\pi=\frac{5}{4}\pi[/tex]
So, the answer will be:
[tex]\frac{5\pi}{4}[/tex]
