Question

pls see the above sum there u have to find angle poa.....

guys pls help!pls​

Answer 1

Answer:

20 degrees

Step-by-step explanation:

According to the laws of reflection, the angle of incidence is always equal to the angle of reflection

now the three angle are standing on a straight angle AOB whose measure is 180 degrees

Therefore since two angles are equal let them be 2x

Now 2x+140= 180 degrees

Therefore anglePOA= angle POB= 20 degrees
