60, because 120 is bigger than a right angle, and the picture shows that it is definitely smaller than a right angle.
For 9. the third table and for 10. the second table
You can add them like this:

first put them in order from biggest to smallest
213
156
+109
-----------
then add:
¹ ← ←
213 ↑
156 ↑
+109 ↑
---------↑ ( carry the 10 )
478 (add the ¹ )
then you get the answer 478!
hope that helps :)
