In the diagram below, A is on line segment CE, and AB bisects angle DAC (meaning that AB splits angle DAC into two equal angles). If DA is parallel to EF and angle AEF = 10 angle BAC - 12 degrees, then what is DAC in degrees?

No diagram.

hi. this is AOPS class content homework. Plz work on it by urself instead of trying to get answers.

The answer is 32 degrees.

Thank you helpful--at last

10*BAC -12+2BAC=180 right

AOPS is supposed to be difficult, it is best to work it out on your own so you actually understand the material
