hint

OpenStudy (samirahdanyel):

so BCD is also 53 degrees?

jimthompson5910 (jim_thompson5910):

no

angle BAD = angle BAC + angle CAD angle BAD = 53+53 angle BAD = 106 degrees angle BAD + angle BCD = 180 degrees

so you divide 180/106

jimthompson5910 (jim_thompson5910):

no

jimthompson5910 (jim_thompson5910):

angle BAD + angle BCD = 180 degrees 106 + x = 180 x = ??

OpenStudy (samirahdanyel):

its 74
