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 co-terminal with the given angle: -40°. I have no idea what co-terminal 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

tan 45 = 1 = a/b

c^2 = a^2 + b^2 4 = 2a^2 a^2 = 2 a and b = sqrt2

So when ever it says co terminal and 1 revolution it means you subtract 360?

Okay, thanks for your help!

360 - the angle - they 'end' in same place - hence co-terminal
