segments rt and su are diameters of circle o. what is msrt? 258° 266° 274° 282°
Answer
Explanation:
Step1: Recall circle - arc property
The sum of the measures of the arcs of a circle is 360°.
Step2: Identify known arc measure
We know that one of the arcs, say arc $RU$ has a measure of 94°.
Step3: Calculate $m\overparen{SRT}$
Since $\overparen{SRT}$ is the major arc and $\overparen{RU}$ is the minor arc, and they together make up the whole circle. So $m\overparen{SRT}=360^{\circ}- 94^{\circ}$. $m\overparen{SRT}=266^{\circ}$
Answer:
266°
