Anything coterminal to 160 degrees will be separated by 360 degrees. In other words, simply add/subtract 360 to/from 160 to get a new coterminal angle So one coterminal angle is 160 + 360 = 520 degrees

Coterminal angles Ac to angle A may be obtained by adding or subtracting k*360 degrees or k* (2 Pi). Hence Ac = A + k*360o if A is given in degrees. or Ac = A + k*(2 PI) if A is given in radians. where k is any negative or positive integer.

sorry was delayed a bit Notice how 200 is one of our coterminal angles So if we subtract another 360 from that, we get 200  360 = 560 So the answer is choice C

Find a positive and a negative angle coterminal with a 160° angle. 160° – 360° = –200° 160° + 360° = 520° A –200° angle and a 520° angle are co terminal with a 160° angle.

y = 2.5*sin(2pi*(x4)/12.4) + 1.6 y = 2.5*sin(2pi*(8.5334)/12.4) + 1.6 y = 2.5*sin(2pi*(4.533)/12.4) + 1.6 y = 2.5*sin(2pi*0.3655645) + 1.6 y = 2.5*sin(2(3.14159)*0.3655645) + 1.6 y = 2.5*sin(2*1.14845378) + 1.6 y = 2.5*sin(2.29690756) + 1.6 y = 2.5*0.74776206 + 1.6 y = 1.86940515 + 1.6 y = 3.46940515 So the water depth at 8:32 am is roughly 3.46940515

p and q are 2 points on a unit circle. if an object rotates counterclock wise, from point p to point q, then through what angle in degrees has it rotated?

Notice that cos(pi/6) = sqrt(3)/2 and sin(pi/6) = 1/2 and cos(5pi/4) = 1/sqrt(2) and sin(5pi/4) = 1/sqrt(2) So the two angles in question are: pi/6 and 5pi/4 The difference between these angles are: 5pi/4  (pi/6) = 17pi/12 Therefore, the answer is 17pi/12
