In the figure below, line I is parallel to line m. Transversals t and u intersect at point A on I and intersect m at points C and B, respectively. Point X is on m, the measure of < ACX is 130 degrees, and the measure of < BAC is 80 degrees. Find all the missing angel measures in the figure. Be sure to include your justification.

Answer then explain why you did it.
