1.	The diagram in Fig 4.18 shows an incident ray AO and the reflected ray OB from a plane mirror.The angle AOB is 30°. Draw normal on the planemirror at the point O and find :(a) the angle of incidence(b) the angle of reflection
Answer» 1)752)75Explanation:So,180(The STRAIGHT ANGLE) -30 = 150Then 150/2=75And as we know angle of INCIDENT and reflection are equalPLEASE MARK IT THE BARINLIEST
