MN is tangent to the given circle at M, MR and MQ are two chords. IF QNM is 60o and MNQ is 40o. Find RMQ
A.
120o
B.
110o
C.
60o
D.
20o
Correct answer is D
QMN = 60o
MRQ = 60o(angle in the alternate segment are equal)
MQN = 80o(angle sum of a \(\bigtriangleup\) = 180o)
60 = x = 80o(exterior angle = sum of opposite interior angles)
x = 80o - 60o = 20o
RMQ = 20o
