Question

1. In a adjoining figure the bisector of angleA and angleB meet in a point O. If angleC = 100° and angleD = 60°. Find the measure of ang AOB





Plz give me answer I will mark you brainalist​

Answer 1

Answer:

60°+100°+angleA+angleB=360°

AngleA+angleB=200°

1by2 angleA+1by2 angleB=100°

Therefore,

angleADB+angleABO+angleACO=180°

100°+angleAOB=180°

angleAOB=180°-100°

angleAOB=80°

ANSWER:80°

Answer 2

Answer:

a=100' and d=60' find the measure of any Aob
