Answer:
Step-by-step explanation:
Sum of exterior angles of any Polygon = 360°
23. x + 65 + 106 + 78 = 360
x + 249 = 360
{To find the value of x, subtract 249 from both sides}
x = 360 - 249
x = 111°
_________________________________________
24. x + x + 59 + 48 + 50 + 39 + 58 = 360
2x + 254 = 360
2x = 360 - 254
2x = 106
x = 106 ÷ 2
x = 53°
____________________________________________
25. 2x + 3x + 44 +85 + 71 = 360
5x + 200 = 360
5x = 360 - 200
5x = 160
x = 160 ÷ 5
x = 32°
_______________________________________________
26. x+ 2x + 77 + 40 + 45 = 360
3x + 162 = 360
3x = 360 - 162
3x = 198
x = 198 ÷ 3
x = 66°
