Answer:
y=5x
Step-by-step explanation:
The table is given as:
x | y
2 | 10
4 | 20
6 | 30
8 | 40
A proportional relation satisfy the relation: 
We can substitute any x value with the corresponding y-value and solve for k.
When x=2,y=10
This implies that:

Divide both sides by 2 to get:

Hence the equation is 
4, there are 4 equal angles
