Answer:
Step-by-step explanation:
The perimeter of a shape or plane figure is the distance round the shape. The diagram of the circle and the triangle ABC formed is shown in the attached photo.
To determine the length of AC, we would apply the Pythagoras theorem which is expressed as follows
Hypotenuse^2 = opposite ^2 + adjacent ^2
AC = hypotenuse
Opposite = 3
Adjacent = 3
AC^2 = 3^2 + 3^2 = 9 + 9 = 18
AC = √18 = 4.24
BX = AX = 3(they are both radii)
BC = AC = 4.24
The perimeter of triangle ABC would be
3 + 3 + 4.24 + 4.24 = 14.48
