The solution of this question will make use of the Two Tangents from Point Theorem which states that "the measure of an angle formed by two tangents drawn from a point outside the circle is half the the difference of the intercepted arcs".
We can also see that the measure of arcs are:
and
Thus, as per the theorem, the measure of the
can be calculated as:

Therefore, we get:

Thus, out of the given options, option B is the correct option.
Answer:
D
Step-by-step explanation:
Y = ax² + bx + c is the equation of a parabola:
y = 4x² -8x -6 is our equation.
The axis of symmetry in a parabola is x = -b/2a
x = -(-8)/(2.4) = - 8/8 and x = - 1 (axis of symmetry
Answer:
a
