Answer:
B. g(x) is shifted 5 units right and 2 units up from f(x).
20%of £800 is 800÷5 =160
800 + 160 =960
The angle between the segment labled x and the chord labeled 30 is not specified. The measure of x cannot be determined, except to say that it is somewhere between 16 and the radius of the circle, √(16²+15²) = √481 ≈ 21.93.
_____
If the angle between x and the chord were marked as a right angle, one could say x=16, because all chords of the same length are the same distance from the center of the circle.
