title: Get the slope from one point and an angle in degrees
body: <p>In javascript, I am trying to draw a line that is at an angle that is user defined.</p>
  
  <p>Basically, I have a point (x,y) and an angle to create the next point at. The length of the line need to be 10px. </p>
  
  <p>Let's say that the point to start with is (180, 200)... if I give it angle "A" and the (I guess)hypotenuse is 10, what would my equation(s) be to get the X and Y for a slope?</p>
  
  <p>Thanks for your help!</p>
