Answer:
2. 180-115 = <u><em>65</em></u>
3. angle = 90-37 = <em><u>53</u></em>
4. angle = 90 - 15 = <em><u>75</u></em>
5. angle = 90-43 = <em><u>47</u></em>
6. 109+71 = 180 = S
7. 19+71 = 90 = C
8. 89+1 = 90 = C
9. 34+56 = 90 = C
10. 75+75 = 150 = N
11. 16+74 = 90 = C
12. 90+90 = 180 = S
13. 65+115 = 180 = S
