let me do it in a different color a color different from the unit circle so i'm going to drop a right triangle here that's 90 degrees this magenta line has gone straight down and if we can figure out the base if we can figure out this distance, let me do it in a different color here, if we can figure out this blue distance we know that it's in the negative direction so if this blue distance is what ever it might be, the negative value of that because we're going to the left of the origin is going to be our x coordinate and whatever this height is in magenta that's going to be out y coordinate do you see it right over here so the x coordinate is where ever this blue distance takes us to the left the height in magenta is out y coordinate so lets think about what we know about this triangle right over here so my first question to you is what is the
