The angle between a tangent and a chord is 14degrees19'16''. If the length of the arc subtended by the chord is 5cm, what is the radius of the circle. Help please, I really have no idea. Can you show it with illustrations, thanks!

HI take a look at the diagram i attached . s=5 , r=?? , Remember these 2 properties of circle (1) angles of alternate segment are equal (red) (2) angles at radius is twice the angle at circumference (blue) Then use this formula , to get r .
