Answer 1

Answer:

“Even the worst days have an ending, and the best days have a beginning.” ...

Answer 2

Answer:

we have,

angle AOB+angle BOC=180°(linear pair)

angle AOB=angle BOC(may be given)

so,

angleAOB+angleBOC=180°

=>angle AOB+angleAOB=180°

=>2×angleAOB=180°

=>angleAOB=180°/2

=>angle AOB=90°
