Question

solve the 10th question

Answer 1

$36°=x \:\:(vertically\: opposite\:angle)\\ x+y=180° (linear\: pair)\\ 36°+y=180°\\ y=180-36\\ y=144\\\\ thanks$

Answer 2

angle COB = angle AOD = 36° ( V.O.A.)
=> angle COB = angle x = 36°

angle AOC + angle COB = 180° ( Linear Pair )
=> angle y + 36° = 180°
=> angle y = 180° - 36°
=> angle y = 144

angle AOC = angle BOD = 144° ( V.O.A. )
=> angle y = angle z = 144°
