question number 18
angle DAC + angle DAB=180 .. (angles in linear pair)
let angle DAC be x
angle DAB be y
x+y=180
angle FAD=angle FAC .. ( given)
angle FAD + angle FAC = angle DAC
angle DAE=angle EAB
angle DAE + angle EAB=angle DAB
angle DAC+angle DAB=180
angle DAC/2=angle FAD
angle DAE/2=angle EAD
angle EAD+angle FAD=angle EAF
angle DAE/2+angle DAC/2=angle EAF
(angle DAE+angle DAC) /2=angle EAF
180/2=angle EAF
angle EAF=90
question number 18
angle COB=angle AOD .. (opposite angle)
angle AOD=63
X=63
COB+BOD=180.. (angle in linear pair)
BOD=180-63=117
Y=117
Y=Z.. (opposite angle)
Z=117
hope it helps you
