Pls help

Step-by-step explanation:

< PRS = 123°

<QOP = x

Now

< PRS + <QRP = 180° { Being linear pair }

123° + <QRP = 180°

<QRP = 180° - 123°

< QRP = 57°

< QOP = x

= 2 * < QRP < angle at the centre is twice the angle at the circumference >

= 2 * 57°

= 114°

Therefore x = 114°

Hope it will help :)❤

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
