Answer:
x = 24°
Step-by-step explanation:
To find 'x', the Alternate Exterior angle postulate will need to be used.
'4x + 9' and '2x + 27' are alternate exterior angles. Therefore, they must sum up to 180.
180 = 4x + 9 + 2x + 27
Combine like terms:
180 = 6x + 36
144 = 6x
x = 24°

The external angle at the intersection of two secants is half the difference of the intercepted arcs. That is
∠E = (1/2)(4x° -2x°) = x°
The given measure of arc AB tells you
... 4x° = 56°
... x° = 14°
The appropriate choice is ...
... B. 14°
