Question

2.
In the given figure, angles subtended by
chords AC and BC at the centre o of the
circle are 55 and 155 respectively. Find
angle АСВ.
(A) 150
(B) 75
(C) 62
(D) 60
В​

Answer 1

Answer:

option b

Step-by-step explanation:

since the total angle at the centre made by AB = 210

so we are looking an angle made by the arc AB

at point C

so the angle made arc AB at centre is 360-210= 150

so the angle at the circumference = 1/2 of the angle at centre

= 150/2= 75

Answer 2

Answer:

75° is the correct answer
