Angle bac=90 (as angle substended by a semi circle is right angle)

then applying angle sum property in triangle abc, we get angle abc=60

AS BC A DIAMETER IT'S BOTH ENDS WILL ALWAYS MAKE RIGHT ANGLE AT CIRCUMFERENCE OF CIRCLE EXCEPT AT POINT B AND AT C.....

SO,
AS WE KNOW ∆ ABC IS A RIGHT ANGLE TRIANGLE...

/_ C = 30°

/_ A = 90°

/_A + /_ B + /_C = 180°

SO /_ B = /_ ABC = 60°
