Answer 1

Answer:

plzz give me brainliest ans and plzzzz follow me

Answer 2

GIVEN :

$\angle{POR}\:+\:\angle{QOS}$ = 105° and OP and OQ are opposite rays.

FIND :

$\angle{ROS}$

SOLUTION :

Now.. POQ is a line.

So,

=> $\angle{POQ}\:+\:\angle{ROS}\:+\:\angle{SOQ}$ = 180°

Now.. $\angle{POR}\:+\:\angle{QOS}$ = 105°

=> 105° + $\angle{ROS}$ = 180°

=> $\angle{ROS}$ = 180° - 105°

=> $\angle{ROS}$ = 45°
