Need help with this ASAP - curvy figure

[Anonymous]

Ok so I need to do this: 

But I am really confused with all the curves. I started it and it doesn't look smooth whatsoever like how it looks in the above picture. Here's what i have:
 

I'm mainly confused on the radii parts. I made circles using the given radii. Is that what I am supposed to do? Any guidance? Thanks!

The first drawing is wrong.

The centres of the arcs are fixated and are positioned delta X +7.5 mm and delta y -63 mm to each other. That creates a diagonal distance of 63.44 mm. To get them tangent to each other the distance needs to be R1+R2 = 73,5 mm.

The annotations of the first drawing are also incomplete. It needs either the length of the vertical line on the left, or the angle to the line above.

oh that makes sense. So the drawing I'm supposed to copy has wrong dimensions and stuff? I got it off online cuz I need practice in this type of stuff. I guess I should have double checked its credibility. Thanks

It's wrong and also incomplete for not provided the angle of the line on top of that drawing.
