In the diagram at the right the segments shown are tangent to the circle Find the value of x
As seen in the diagram
DB and EB are tangents to the circle at B
DB=EB=2
Similarly
EC=FC=3
BC=BE+EC=2+3=5cm
In the following diagram, and are tangents to the circle. Find the value of: a) ∠AOB b) ∠OBA given = 7 cm.
