waecmaths question:
The diagram is a circle centre O, If $\angle SPR=2m$ and $\angle SQR=n$ express m in terms of n
Option A:
$m=\tfrac{n}{2}$
Option B:
m = 2n
Option C:
m = n - 2
Option D:
m = n + 2
waecmaths solution:
Assume the triangle SPR and SQR are cyclic triangle, both have the same base SR and point P and Q on the circumference of the circle. It implies that $\angle SPR$and $\angle SQR$are on the same segment. Therefore 2m = n, m = $\frac{n}{2}$
