Question

please fast please help me ​

Answer 1

Step-by-step explanation:

angle POS = x

therefore angle POR= angle ROS = x/2 (because OR is angle bisector)

now since angle POS = x, angle SOQ =180-x

angle SOT= angle TOQ = (180-x)/2= 90-x/2 (because OT is also angle bisector)

therefore

angle ROT = x/2 + 90 - x/2 = 90
