Answer:
m(arc RT) = 148°
Step-by-step explanation:
From the picture attached,
Segment RT is a chord and segment RS is a tangent of a circle O meeting at R.
By the property of tangent chord angle,
"Angle formed by an intersecting tangent and chord measures half of the intercepted minor arc"
m(∠SRT) = [tex]\frac{1}{2}(\text{minor arc RT})[/tex]
[tex]74^0=\frac{1}{2}m(RT)[/tex]
[tex]m(\text{arc RT)}=2(74^0)[/tex]
[tex]=148^0[/tex]
Therefore, measure of minor arc RT is 148°.
