Point Q is the center of Circle Q in the diagram below. The measure of angle XAY is 72° (m∠XAY = 72°). Since the measure of the intercepted arc XY is 144°, a student named Naomi mistakenly claims that the measure of ∠XBY is also 144°.
a. In a short paragraph, explain the source of Naomi’s error. In your response, be sure to describe the problem in terms of the following two formulas:
inscribed angle = 1/2 · (intercepted arc) and
intercepted arc = central angle.
Be sure to use important vocabulary like “inscribed angle,” “central angle”, and “intercepted arc”.
b. Make an estimate of the degree measure of ∠XBY. Justify your answer.
