in a quadrilateral ABCD AO and bo are the bisector of angle A and Angle B respectively angle C is equal to 70 degree and Angle b is equal to 30 degree then angle aob is equal to


plz solve it step to step wise plz plz plz
it's answer is 50degree​

Answer 1

Answer:

i got it

Step-by-step explanation:

60°

Angles A+B+C+D =360

Therefore A+B = 240

In triangle AOB sum of angles is 180

A/2 + B/2 +O = 180

(A+B) /2 =120

O=60

Answer 2

70+30=100

by theorem

100/2

50
