In the following diagram if AB=BC and CD=DE, find the value of Angle GCF?

In the given figure, if AB = AC, then what is the value of ∠ACB – ∠DBF?

If segment AB is a straight line then what is the value of a + b?

In the picture you will see three circles inside a rectangle. The diameter of all the 3 circles are given, based on which you are supposed to find the length of AB.

Find the length of AB in the given picture.

If in the following image AC is the diameter of the circle where AB = 4cm and BC = 1cm. Find the x?
