Angle C is an inscribed angle of circle P. Angle C measures (20x – 5)° and arc AB measures (30x + 30)°. Find the measure of arc AB.

Question

anonymous · Answer

The measurement of the arc of an inscribed circle is twice the measurement of the inscribed circle.

anonymous · Answer

Therefore (30x + 30) = 2(20x -5)
Solve for x,
Then to find the measurement of the arc, plug in the value of x to 30x + 30

Please post a diagram so that the location of arc AB can be seen.

It is NOT given that angle C cuts off (intercepts) arc AB.
