Angle R is an inscribed angle of a circle. Use the attached theorem to get the measure of the arc it cuts off. The intercepted arc is in blue.

The measure of an inscribed angle is how related to its intercepted arc?

Read the part of the attachment that says that the measure of the inscribed angle is ...... ? What comes next?

so multply it by two?

DirectrixBest ResponseYou've already chosen the best response.1
Yes. So if angle R is 23, what is the measure of arc NQ ?

DirectrixBest ResponseYou've already chosen the best response.1
Yes. Next, do you see that central angle O cuts off the same arc that angle R did?

DirectrixBest ResponseYou've already chosen the best response.1
No, the central angle is not 23. On the previous problem, what did we say is the measure of the central angle of a circle in relation to its intercepted arc?

DirectrixBest ResponseYou've already chosen the best response.1
No, that was the inscribed angle. We're talking central angles.

Because they are congruent right?

There is a little bit more to it. You don't know that the angles are congruent right off the bat. Look at the two congruent chords of the circle that go with the arcs cut off by the two central angles. Because in a circle, congruent chords have congruent arcs and the two central angles cut off congruent arcs, their measures are the same.

Would it be 9.2 or 85???
 8 months ago

DirectrixBest ResponseYou've already chosen the best response.1
x^2 = 85 x = 9.2? Yes.
