In the diagram O is the centre of the circle of... - WAEC Mathematics 2014 Question
In the diagram, O is the centre of the circle of the circle, PR is a tangent to the circle at Q < SOQ = 86o. Calculate the value of < SQR.
A
43o
B
47o
C
54o
D
86o
correct option: a
Construction: draw a line from Q to point P and another line from S to point P.
< SOQ = 2< QPS (< at centre is twice < on the circumference)
< QPS (\frac{86}{2} = 43)
< SQR = < QPS ( < between a chord and tangent = < in the alternate segment)
< SQR = 43o
