Geometry - Angle Construction

I need to construct a 75 degree angle. I was thinking I could get a 45 degree angle by drawing a right angle and bisecting it, but I'm not really sure on how to get a 30 degree angle. Am I going about this wrong?

  2. A 45 degree angle is 3, 15 degree angles. Divide the 45 by 3 = 15.
    So, make a 45 degree angle & add...
    45+15=60
    60+15=75

    I put the wrong angle measure on my earlier question. It should have been... How many different triangles, if any, can be drawn with on 20 degree angle, one 45 degree angle, and one 115 degree angle. Thanks....
