(D) 360 + a
(E) 360 – a

Shorter answer: Angles around a point always sum to 360°
x + a = 360
x = 360 - a

Answer E

Longer answer: Extend L2 to the right.

L1 and L2 are parallel lines (given) cut by a traversal. Alternate interior angle measures are equal.

Where L2 and the transversal meet (a point around which there are 360°) there is an alternate interior angle that = a:

\(_{L2}\)________a/

And x is the measure of the portion of the 360° that does not include a, i.e., all the degrees below L2 and to the right of the transversal:

\(_{L2}\)_________/\(_{x}\)

x + a = 360
x = 360 - a

Answer E
