Question

in the following figure BC= radius OB find the value of angle OCB

Answer 1

Dear student,
It has been given that there is a triangle in which
all sides are equal ,as two sides are the radii and the length of third side is given as equal to the radius,i.e.:
BC=OB=OC=radius
We all know that all angles in an equilateral triangle are equal to 60°.
Hence, <OCB = 60°.
Regards.
