Correct Answer: Option B
Explanation:
OQ = OR = radii
< ROQ = 180 - 86 = 84o
\(\bigtriangleup\)OQR = Isosceles
R = Q
R + Q + 84 = 180(angle in a \(\bigtriangleup\))
2R = 96 since R = Q
R = 48o
ORQ = 48o
OQ = OR = radii
< ROQ = 180 - 86 = 84o
\(\bigtriangleup\)OQR = Isosceles
R = Q
R + Q + 84 = 180(angle in a \(\bigtriangleup\))
2R = 96 since R = Q
R = 48o
ORQ = 48o
