Answer:
23.) x = 111
24.) x = 53
25.) x = 32
26.) x = 66
Explanation:
The sum of the exterior angles of a polygon is 360°.
23.)
65 + 106 + 78 + x = 360
249 + x = 360
x = 111
24.)
50 + 48 + 59 + x + x + 58 + 39 = 360
254 + 2x = 360
2x = 106
x = 53
25.)
85 + 44 + 3x + 2x + 71 = 360
200 + 5x = 360
5x = 160
x = 32
26.)
40 + x + 77 + 2x + 45 = 360
162 + 3x = 360
3x = 198
x = 66
