Perimeter of a triangle and a segment?
![enter image source here]()
The diagram shows a sector of a circle with radius r cm and centre O . The chord AB divides the sector into a triangle AOB and a segment AXB . Angle AOB is theta radians.
(i) In the case where the areas of the triangle AOB and the segment AXB are equal, find the value of the constant p for which theta = p sintheta .
(ii) In the case where r = 8 and theta = 2.4 , find the perimeter of the segment AXB .
