In the diagram, O is the centre of the circle, < QPS = 100o, < PSQ = 60o and < QSR. Calculate < SQR

A.

20o

B.

40o

C.

60o

D.

80o

View answer & explanation

Correct answer is A

In the diagram, < RPQ = 80o(angles in same segment)

< SPR = 100o - < RPQ

= 100 - 80

= 20o

< SQR = < SPR = 20o (same reason as above)

< SQR = 20o
