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.
that's how i see it.
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 :)
it's 60 degrees because all equilateral triangles have angles of 60 degrees since all the
angles are equal, x + y + z= 180 deg, since <x is equal to <y which is equal to <z, then we could say <x + <x + <x = 180 degrees, so, 3<x = 180 degrees, divide both sides by 3, thus <x = 60 degrees
why does OC=OB imply x is at angle C???
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?
