\huge\mathcal{Given}

PQ is a chord of a circle with centre O.

∠qpt = 60 {}^{0}

let X be the point to the tangent PT.

∠qpt + ∠opt = 90

↬∠opt = 30 {}^{0}  - ∠qpt = 90 {}^{0}  - 60 {}^{0}  = 30 {}^{0}

In ∆POQ

∠poq = 180 - (∠opq - ∠pqo) = 180 - 30 - 30 = 120 {}^{0}

Minor arc ∠POQ=120°

∠poq = 360 {}^{0}  - 120 {}^{0}  = 240 {}^{0}

Using tangent-secant theorem

∠qrp =120  {}^{0}

Answer:

Answer:

answer is 120

Step-by-step explanation:

given :PT is a tangent so ZOPT=90

ZQPT =60

ZOPQ = LOPT-ZQPT

ZOPQ=90-60

ZOPQ=30

ZOPQ+2OQP+POQ=D180

PROPERTY)

ZPOQ= 1803030

(ANGLE SUM

ZPOQ=120 Angle OPQ= angle OQP = 30° ie.,

Angle POQ= 120°. Also, angle PRQ= 12 reflex angle POQ.

ZPRQ=1/ 2(360-120)
