Answer:
b = 30 degrees
a = 150 degrees
Step-by-step explanation:
Let's call a to the first angle and b to the second one. So we have:
a = 5*b (1)
and it says that the greater angle has 120 degrees more than the lesser angle. So It will be:
a = 120+b (2)
We just need to solve both equations. We can equal both of them.
5b = 120+b
4b = 120
b = 30 degrees
Therefore a = 5*30 = 150 degrees
a = 150 degrees
