Two circles meet at their radius distance

Say I would like to draw two circles with different diameter or radius. As in the picture, say that the diameter (D1) = 60, Diameter 2 (D2) = 40 (hence R1=30, R2=20). So, the distance between their center will be 30+20=50, as they meet exactly in one point. The two circles are drawn above the same plane, say, above a horizontal plane. I tried 4 tangential options from circle drawing menu, but didn't work. Of course I can do it by do some maths. But what I am asking here is how to do without doing that math, just as simple as using that tangential.

Best regard,
