Find the reference angle theta Round your answer to four de

Find the reference angle theta \'. (Round your answer to four decimal places.) theta = 11.7 theta \' = rad

Solution

Here Theta is in first quadrant

And for the theta in first quadrant,the reference angle is the theta itself

Therefore reference angle=11.7 degree

And we need to convert it to radian

And to convert it to radian ,we need to multiply it by Pi/180

Where pi=3.14

Therefore reference angle =11.7*3.14/180

                                          =.2041 radian
