Question

PLS REPLACE QS WITH OS PLS HELP FAST

Answer 1

Step-by-step explanation:

given:_ <ROQ = 90°

or < POR = 90°

To prove _ < ROS = 1/2 ( <QOS - <POS )

Proof __

< QOS = 90° + < ROS

< QOS = <POR + < ROS ( Because < POR = 90° )

<QOS = (<POS + <ROS) + <ROS

<QOS = <POS + 2<ROS

Now, 2<ROS = < QOS - < POS

SO, < ROS = 1/2 ( <QOS - < POS )

Hence PROVED
