Answer:
to find <A and <B WE WILL FOLLOW FOLLOWING STEPS
Step-by-step explanation:
in triangle OAB
<OAB +<OBA+<AOB =180
<OAB=<OBA{RADIUS MAKES EQUAL ANGLE }
THEREFORE , <OAB +<OAB+ <AOB = 180
2<OAB +<AOB=180
2<OAB +130 = 180
2<OAB = 180 - 130
2<OAB= 50
<OAB = 50/2
<OAB = 25
THEREFORE <B=25
AND TOB FIND ANGLE A
We know that angle around a point is 360 degree
therefore <a +<AOB=360
<a +130 =360
<a=360-130
<a=230
