Question

6. In a quadrilateral ABCD, if AO and BO be
the bisectors of A and B respectively,
angleC = 70° and angle D= 30° , then angle
AOB is​

Answer 1

Answer:

(see da attached picture)

Explanation(in short):

2a°+2b°+70°+30°= 360° (in ABCD)

.............................................................................

Then,

» 2 (a+b+50)° = 2•180°

» (a+b)° = 180° - 50°

» 180° -∠AOB = 180° - 50°

» ∠AOB = 50° [Ans.]

Answer 2

Answer:

answer is 50 degrees.

since AO and BO is angle bisector of angle A and B respectively so in triangel AOB the angle subtended by A and B in AOB is 130 degrees .

so AOB =50
