mmmh???
I could do a
30°, 45°, 60° , 90° , 75°, 105°, 120°, 135°, 150°, 165°
Can you see any I missed ?
using two triangle rulers with angles of (30, 60, 90) and (45 , 45, 90) how many angles less than 180 degrees can be drawn?

That would be 145 degrees.
11 combinations in total! Thanks for your help Reiny, I appreciate it.

How would you get 145°
Mistaken, I did 30 + 105 and thought it was 145 :P thanks for your help though.
There are actually more than what I gave you.
Mine are only from the addition of these angles.
How about subtractions ?
e.g. 45 - 30 = 15
Can you find some more?

You are a genius! 15 is the last one.
