Answer:
11. 130°, obtuse angle
12. 40°, acute angle
13. 90°, right angle
14. 110°, obtuse angle
15. same as 14, I guess?
Step-by-step explanation:
questions 11, 14, 15 - an obtuse angle is an angle greater than 90° but less than 180°
question 12 - an acute angle is an angle that is less than 90°
question 13 - a right angle is exactly 90°
in question 14 the angle starts at 30° and ends at 140° so you subtract 30 from 140
hope this helps :)
