the answer Would be 45degree
yashrajsinh:
can you write a step
since AOB is diameter then angle C = 90degree also ac=cb=x (let) then 2x+90=180 then x=45
thanks
pleasure

AOB is the diameter.
==> angleACB=90°
AC=BC
==> angleCAB=angleS
In triangle ABC,
angleABC + angleBCA + angleCAB =180°
angleCAB + 90° + angleCAB = 180°
2*angleCAB + 90° = 180°
angleCAB = 90°/2
angleCAB = 45°
==> angleACB=90°
AC=BC
==> angleCAB=angleS
In triangle ABC,
angleABC + angleBCA + angleCAB =180°
angleCAB + 90° + angleCAB = 180°
2*angleCAB + 90° = 180°
angleCAB = 90°/2
angleCAB = 45°
thanks
