d+e+f =180°
40°+70°+f =180°
110°+f =180°
f=70°
given bisectors of e and f joins at o,in triangle eof,
1/2(70°)+1/2(70°)+eof =180°
35°+35°+eof =180°
70°+eof=180°
eof=110°
40°+70°+f =180°
110°+f =180°
f=70°
given bisectors of e and f joins at o,in triangle eof,
1/2(70°)+1/2(70°)+eof =180°
35°+35°+eof =180°
70°+eof=180°
eof=110°
