Find the
value of y in the figure below. [Diagram not to scale]

__Solution__
Angle at the
centre = 2 x (angle at the circumference

= 2 x (y)

=2y

Angle 2y and
8y are opposite angles. They add up to 360

^{0}.
Therefore 2y
+ 8y = 360

^{0}^{}

10y = 360

^{0}^{}

__10y__=

__360__

^{0}

10 10

y = 36

^{0 }
Hence y = 36

^{0 }
