Radians, perimeter and area of shaded region
Hi there...
I need some help...
Question is as follow:
The diagram shows a circle with centre O and radius 8cm. Points A and B lie on the circle. The tangents at A and B meet at the point T and AT = BT = 15cm
1. Show that AôB - 2,16 radians, correct to two decimal figures.
2. Find the perimeter of the shaded region
3. Find the area of the shaded region
I've got formulas for perimeter and area, but I don't know what the angle of T is...

Hi;
What diagram? Please provide the link or copy the diagram.
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
