Question

pls solve the 31,32,33 "urgent" question need fast

Answer 1

32.

∠POS + ∠QOS = 180                 -------------1

∠POS + ∠ROS = 90

Multiplying both sides by 2

2∠POS + 2∠ROS = 180         ------- 2

From eq 1, 2

∠POS + ∠QOS                  = 2∠POS + 2∠ROS

∠QOS + ∠POS - 2∠POS  = 2∠ROS

∠QOS - ∠POS                  = 2∠ROS

1/2 (∠QOS - ∠POS)           = ∠ROS
