hi,the teacher went over this question but i didnt really understand it:the shape shown in figure 1(a sector with a circle in the middle and 60 degrees as the angle at the the top of sector) is a pattern for a pendant. It consists of a sector OAB of a circle centre O,of a radius 6cm,and angle AOB=60 degrees.The circle C,inside the sector, touches the two straight edges,OA and OB,and the arc AB as shown.Find the radius of circle C.
What's the length of OX? And in terms of r? And take it from there.
Hope this makes sense! Feel free to ask any questions
