Two chords QR and NP of a circle intersect inside the circle at x. If RQP = 37o, RQN = 49o and QPN = 35o, find PRQ
35o
37o
49o
59o
Explicaţie
In PNO, ONP
= 180 - (35 + 86)
= 180 - 121
= 59°
PRQ = QNP = 59°(angles in the same segment of a circle are equal)
= 180 - (35 + 86)
= 180 - 121
= 59°
PRQ = QNP = 59°(angles in the same segment of a circle are equal)
