Question

Find the reference angle for each of the following. Round your answers to four decimal places, if needed. You might find the following approximations useful: pi/2 almostequalto 1.5708, pi almostequalto 3.1416, 3 pi/2 almostequalto 4.7124, 2 pi almostequalto 6.2832 4.2 radians radians 4.84 radians radians -0.15 radians radians squareroot 2 radians radians Find the reference angle for each of the following. Round your answers to four decimal places, if needed. 116.84 degree degrees -300.7 degree = degrees 443.11 degree = degrees 175.8 degree = degrees

Explanation / Answer

4.2 radians (in 3nd quadrant) = 4.2 - 3.1416 = 1.0584

4.84 radians (in 4th quadrant) = 4.84 - 6.2832 = 1.4432

-0.15 radians (in 1st quadrant) = 0.15

square root (2) radians (in 1st quadrant) = 1.4142

116.84 radians (in 2nd quadrant) = 180 - 116.84 = 63.16

-300.7 radians = - 300.7 + 360   = 59.3

443.11 radians = 443,11 - 360   = 83.11

175.8 radians = 180 - 175.8 = 4.2
