Answer:


Step-by-step explanation:
Given

Solving (a): In vertex form
The vertex form of an equation is:

To do this, we make use of completing the square method.
We have:

------------------------------------------------------------------
Take the coefficient of x (i.e. -6)
Divide by 2; -6/2 = -3
Square it: (-3)^2 = 9
Add and subtract the result to the equation
------------------------------------------------------------------



Factorize 


Factor out x - 3

Express as squares

Hence, the vertex form of
is: 
Solving (b): State the coordinates of the vertex.
In
; the vertex is: (h,k)
The vertex of
will be 
The answer you are looking for is an obtuse so it would be more than 90 degrees. may i have brainlest
