Answer:
.
Step-by-step explanation:
We are given
and
are zeros of the polynomial
.
We want to find the value of
if
.
Lets use veita's formula.
By that formula we have the following equations:
(-b/a where the quadratic is ax^2+bx+c)
(c/a)
Let's simplify those equations:

If
and
, then
.
Let's solve this for k:
Subtract 6 on both sides:

Find a common denominator:

Simplify:
.
You should times each side by 3/2, so your answer is C.
1) it's just 360 divided by 8 sectors = 45 degrees (answer B)
2) (180-45)/2 = 67.50 (answer D is the nearest)
