Answer: 0.8 radians
Step-by-step explanation:
To solve this exercise you must apply the formula shown below:

Where S is the arc lenght, r is the radius of the circle and
is the central angle in radians.
Solve for the central angle:

Now, when you susbtitute the value of the arc length and the radius, you obtain that the central angle is:

Answer:
6x + y = 20
Step-by-step explanation:
rise over run is 30 / 5 which is equal to six
Since the line is positive, the 20 is positive
I hope this helps!!
If you want it estimated it would be .55 which would be 55/100 which would simplify to 11/20
