In the diagram, o is the
centre of the circle and
XY is a chord. If the
radius is 5cm and XY=
6cm, calculate the
i angle which X Y subtends at the centre O
i area of the shaded portion
in Major arc XY

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30
