               23) 155°                    24) 323°

Step-by-step explanation:

Use Pythagorean Theorem to find r:     x² + y² = r²

19) x = ,  y = 8,    r = 9

20) x = 3,   y = 4,   r = 5

21) x = ,   y = -3,   r = 4

22) x = ,   y = 7,   r = 8

23) x = -13,   y = 6,   r =

24) x = 4,    y = -3,   r = 5

answer is 144
