Answer 1

Answer:

angle POA+angleAOB+angle BOQ=180°

50°+angle AOB+45°=180°

=> angle AOB={180-(50+45)}°

=> angle AOB=(180-95)°=85°

Answer 2

Answer:

85°

Step-by-step explanation:

This figure describes a linear pair POQ

According to the laws a linear pair always measures 180°

So PQ = POA + AOB + BOQ

Now, we have to put the known values.

180° = 50° + AOB + 45°

180° = 95° + AOB

AOB = 180° - 95°

AOB = 85°

Verifying:

PQ = POA + AOB + BOQ

180° = 50° + 85° + 45°

180° + 135° + 45°

180° = 180°

L.H.S. = R.H.S.

Hence, verified
