Answer 1

Using property sum of Adjacent angles are 180

so <c + <b = 180

70 + <b = 180

<b = 110

BO is bisector of <b so

2 <abo = 110

<abo = 55

<d + <a = 180

<a = 180 - 30 = 150

AO is bisector of <a so

2 <bao = 150

<bao = 75

Now in triangle AOB

<bao + <abo + <aob = 180

75 + 55 + <aob = 180

<aob = 180 - 130 = 50

<aob = 50
