Answer:
see explanation
Explanation:
The sum of the angles around a point = 360°
Subtract the sum of the given angles from 360 for b
(15)
b = 360° - (297 + 35)° = 360° - 332° = 28°
(16)
b = 360° - (296 + 25)° = 360° - 321° = 39°
(17)
b = 360° - (294 + 28)° = 360° - 322° = 38°
(18)
b = 360° - (220 + 101)° = 360° - 321° = 39°
