Answer:
The answer is D.
Step-by-step explanation:
You have to divide it by 2 :
∠RST = ∠ROT ÷ 2
= 46° ÷ 2
= 23°
O represents the centre of circle.
(Correct me if I am wrong)
D. 23°
The measure of central angle is twice the angle of circumference lying on the same arc. So,
<RT = 2(<RST)
<RST = <RT/2
<RST = 46/2
<RST = 23°
