Given:

Consider the below figure attached with this question.

In Circle Y, Chords R T and S U intersect.

Arc RS is 106 degrees.

The angle that intercepts arc RS is 94 degrees.

To find:

The measure of arc(TU).

Solution:

If two chords intersect each other insider the circle, then the half of sum of intercepted arcs is equal to the angle on intersection of those arcs.

For the given problem,


(1)/(2)[m(arc RS)+m(arc TU)]=94^\circ


(1)/(2)[106^\circ+m(arc TU)]=94^\circ


106^\circ+m(arc TU)=2* 94^\circ


106^\circ+m(arc TU)=188^\circ


m(arc TU)=188^\circ-106^\circ


m(arc TU)=82^\circ

The measure of arc(TU) is 82 degrees.

Therefore, the correct option is A.

Circle Y is shown. Chords R T and S U intersect. Arc R S is 106 degrees. The angle-example-1
