The Hamilton path the answer is B
8/5 or 1.6 you just need to find the rise over the run
Firstly we are looking for two variables x,y so that we need two formulas .
the second formula is missing
We can find this using the formula for arc length (where
is the radius of the circle and
is the central angle in radians):

In our problem, we are given
. This means that:

The measure of the angle is 1.5.
