OC and OB are radii of the circle that means they are equal. So we get x at angle C then you use Sum of angles in all triangles to get x which will be equal to 60.
x + x + x = 180.
aren't lines OC and OB radii of the semi - circle? which means they are equal just like in an isoceles triangle the sides are equal which makes the angles equal right?
60 degree
Correct. Proof?

that's how i see it. your welcome
Oh yeah. what an idiot i am :(
Nah bro mistakes happen and that's what makes math interesting and fun!
I've been in your place multiple times and that's why we have a community to help each other out :)
why does OC=OB imply x is at angle C???
