How do i find angle 1 without angle 2 and only the 70?

Angle 1 is vertical to 60° meaning that angle 1 is equal to 60°.

All triangles’ angles always add to 180 degrees. Since angle 1 is across from the angle measuring 60 degrees, angle 1 will measure 60 degrees. To find angle 2, you can add 70 and 60, which is equal to 130, and subtract 130 from 180. In other words. Angle 1 would measure 60 degrees and angle 2 would measure 50 degrees. To find angle 3 you can add 60+40=100 and subtract that from 180: 180-100=80 degrees. Hope that helped!
