1) Assume angle C is a right angle and given the conditions c=2 and angle B = 45 degrees, solve for the side lengths of the right triangle.
When doing the math i got sqrt 2 for sides a and b, Would this be correct?
2) Find a positive angle less than one revolution around the unit circle that is coterminal with the given angle: 40°.
I have no idea what coterminal means..i need a refresher.
3) Draw the angle given in degrees on the unit circle where 0° corresponds to the positive portion of the horizontal axis: 2012°.
What i got was on Q2 which would be 32 degrees
