For those who are having trouble, ADB is a central angle, meaning it’s congruent to the arc, and since inscribed angles of circles are half the arc, he just divided the central angle by 2, since it’s the same as the arc, also it’s a central angle because usually when they have a point to what it looks like the middle of a circle, it’s the center, like every time.

You did not explain why the arc has a measure of 90 degrees. There is a lot that you left out of this explanation. If you are teaching for memorization of this one problem, then you have achieved your goal. If you want understanding that children can use on any problem, you need to be thorough.

Angle at the centre is twice angle at the circumference If D is the center, ❤🎉

Or just use the law of sines and cosines. AC=Sqrt(2-2CosB). And 1/2 of ACB = siny/1=sin130.5/AC. Taking the inverse sin, you get 24.75, times 2 = 49.5

I haven't taken geo yet, but the way I would've solved is just by using the fact that the angles of a triangle always add to 180, to solve for the angles of BAC or ABC, then solve for ACB. (probably wrong, i dunno.)
