intersect at T as
shown.
If
PSR 42 and
m(arc SQ) = 42°;
then ZSTQ = ........
(A) 63 (B) 42
(C) 90° (D) cannot be determined.
guys pls give me detailed explanation...​

Answer 1

Answer:

Given:- In Circle with centre T.

Chord PQ and chord RS intersect at T

angle PSR=42 and m(arc SQ)=42

Answer 2

Answer: B. 42°

Step-by-step explanation:

As by the given question,

As in the figure, chords PQ and RS intersect at T as shown.

As the chords PQ and RS intersect at T. if ∠PSR=42° and m(arc SQ)=42°

As to find ∠STQ

So arc(SQ) can make an angle = 42°

As arc makes this angle at point T

then ∠STQ = 42°

So the correct answer is B- 42°
