Step-by-step explanation:
1. Find the Zeros



2. Factoring Trinomials



.88622692545 so approximately.89
So the hypotenuse is 2.7, and the opposite is 1.6.
We can use sine to find the angle.
sin(x) = (1.6)/(2.7)
Simplify:
sin(x) = 0.592592593
Plug this in your calculator to find the inverse of sine:
x = 36.34120312
So the angle is 36 degrees.
The circumference of the circle is 10.36
