Answer:
16 question ans is 100
17 question ans is 70
18 question ans is 90
19 question ans is 180
20 question ans is 68
16. x = 180° - 100° = 80°
17. z = y = 180° - 50° = 130°
18. y = 180° - (30° + 90°) = 60°
19. x = 180° - 80° = 100°
y = z = 80°
So, x + y + z = 100° + 80° + 80° = 260°
20. y = 112°
Now,
z = x = 180° - (40° + 112°) = 28°
Hope It Helps :)
