Given the quadrilateral RSTO inscribed in the c... - JAMB Mathematics 2017 Question
A
100o
B
140o
C
120o
D
10o
correct option: c
If RST = 60o
RXT = 2 × RST
(angle at the centre twice angle at the circumference)
RXT = 2 × 60
= 120o
RXT = 2 × RST
(angle at the centre twice angle at the circumference)
RXT = 2 × 60
= 120o
