Please help! In circle Y, what is m? 82° 100° 106° 118°

ss7ja [257]

Answer:

The correct option is: 82°

Step-by-step explanation:

In the given diagram, two chords $RT$ and $SU$ are intersecting.

According to the Angle of intersecting chord theorem, "If two chords intersect inside a circle, then the measure of the angle formed is one half the sum of the measure of the arcs intercepted by the angle and its vertical angle."

That means here......

$94\°=\frac{1}{2}(m\widehat{RS}+m\widehat{TU})\\ \\ 94\°=\frac{1}{2}(106\°+m\widehat{TU})\\ \\ 2(94\°)=106\°+m\widehat{TU}\\ \\ 188\°=106\°+m\widehat{TU}\\ \\ m\widehat{TU}=188\°-106\°=82\°$

So, the measure of arc $TU$ is 82°
