Answer:
64°
Step-by-step explanation:
In circle with center P, AD is diameter.

I think y=0 because 6 multiple by 0 is 0 then x= 6 hope this helps might want to check my work to
F(X) = (3x + 5)/X
F(a + 2) = (3(a + 2) + 5)/(a + 2)
F(a + 2) = (3a + 6 + 5)/(a+2)
F(a + 2) = (3a + 11)/(a + 2).
This would be the final solution.
