Hi the value of x=118

ans427: give me solution

sunilpalIwal851: Hi

ans427: hi

sunilpalIwal851: As 30+40+48=118.then.360-118=242i.e. 30+40+48+242=360but x=360-242=118 hence x=118

ans427: why you have subtracted from 360

Ramcharan: because abcd forms a quadrilateral and sum of all angles in a quadrilateral is 360

sunilpalIwal851: Because x+cdb=360 (sum of all angles around a point is equals to 360 degrees

ans427: ok

sunilpalIwal851: Ya both the explanation S are correct

HEY!!!HERE IS YOUR ANSWER

In triangle ABC ,
<A+<B+<C=180°_______by ASP
48°+<B+<C=180°
<B+<C=180°-48°
<B+<C=132°
40°+<DBC+30°+<DCB=132°
<DBC+<DCB=132°-(40°+30°)
<DBC+<DCB=132°-70°
<DBC+<DCB=62°

in triangle DCB ,
<DBC+<BDC+<DCB=180°
62°+<BDC=180°____(since <DBC+<DCB=62°)
<BDC=180°-62°
<BDC=118°

##<BDC=X=118°

HOPE IT HELPS YOU!!!!
