Question

Figure in the attachment is a circle with centre O and PQ is diameter.
Find the sum of Angles PQR, PRS, and PTS.
Note: Use angle Properties of circles...

Kindly Give detailed answer!!​

Answer 1

Step-by-step explanation:

PRST is a cyclic quadrilateral.

so,the sum of the interior opposite angles would be 180°.

so,

PRS+PTS=180°

angle in the semicircle is right angle.

so,PQR=90°

hence,

PQR+PRS+PTS=180°+90°=270°
