Question

in a parallelogram ABCD, the diagonals bisect each other at O. If angle ABCD =30°, angle BDC=10° and angle CAB=70°.Find :angleDAB, angle ADC, angle BCD , angle AOD, angle DOC, angle BOC , angle AOB, angle ACD, angle CAB, angle ADB, angle ACB, angle DBC and angle DBA​

Answer 1

Answer:

Step-by-step explanation:

ACD=BAC=70°,

ABC=ADC

30°=10°+BDA

BDA=20°,

ADC=20°+10°=30°,

ADC+DAB=180°

30°+70°+DAC=180°

DAC=80°,

DAC=ACB=80°
