Question

AB || CD find x°
please explain don't write direct answers plzzzzzzzzzzzz​

Answer 1

Answer:

AB||CD

draw a line EF passing through O.

therefore, AB||EF||CD

angle ABO=40°

angle EOB+angle ABO=180°(supplementary angles)

angle EOB+40°=180°

angle EOB=180°-40°

angle EOB=140°

angle CDO=35°

angle EOD+ angle CDO=180°(supplementary angles)

angle EOD+35°=180°

angle EOD=180°-35°

angle EOD=145°

angle EOD+angle CDO=x

145°+140°=x

285°=x
