Answer:
Equation 1
6*a = 360°
Equation 2
2*a + 2*b = 360°
a = 60°
b = 120°
Step-by-step explanation:
From the first picture we can see that 6 angles a° made a complete circle, that is, 360°. So:
6*a = 360°
a = 360°/6 = 60°
From the second picture we can see that 2 angles a° and 2 angles b° made a complete circle, then:
2*a + 2*b = 360°
2*b = 360° - 2*60°
b = 240°/2 = 120°
