PLZZZZZ SOLVE IT.. ITS ICSE 10TH QSTN... PLZZZZ​

Answer 1

Answer:

I think the answer is 58degree

Answer 2

From figure :

∠PSQ = 90°.

Also,

∠SPR=1/2 ∠ROS.

(Angle at the centre is double the angle at the circumference subtended by the same chord).

Now,

SPT =1/2 * 42°= 21°

∴ In right triangle PST,

∠PTS = 90° - ∠SPT

⇒ ∠RTS = 90°- 21° = 69°

Hope it helps!
