Question
In a circle with centre O, PAX and PBY are the tangents
to the circle at points A and B. from an external point P. Q is any point on the circle such that <QAX = 59° and <QBY = 72°. What is the measure of <AQB?Solution
Alternate segment theorem for ΔAQR, => <ARQ = <QAX Same for ΔQBR, => <BRQ = <QBR => <R = 59˚ + 72˚ = 131˚ Now, => <Q = 180˚ - <R => <Q = 180˚ - 131˚ => <Q = 49˚
