What is the reference angle of -3 radians? explain.

Reference angle of -3 radians is α= - 171° 53 min 15 sec .

We know the formula for calculating circular arc

Let l=circular arc which ic according to central angle of the circle α

l=((2R π)/360)α  Let l=1 radian and R=1 (unit circle with radius R=1)

1= ((2π)/360)α => α= 360/(2π)= 180/π= 57° 17 min 45sec

Angle of the 1 radian is equal to angle 57° 17min 45sec

According to this

angle of the  -3 radians = -3 ( 57° 17min 45sec) = - 171° 53min 15sec

when you count in the clockwise direction.

Good luck!!!

step-by-step explanation:

.6 is 1/2 of 12

the answer is actually d. i just took the test

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
