Geometry - Ch. 6: Circles (19 of 39) Tangent Lines: Another Example

To donate:

We will find x=?, an external angle that is outside of a circle, then the measure of the angle is ½ (half) the measure of the intercepted arc.

Excellent explanation Sir. Thanks 🙏🙏🙏🙏🙏🙏

For whatever reason I was able to look at the problem and add 90+90+130 and subtract that total, 310 from 360 to arrive at 50° for x. Intuitively it made sense.
I have no geometry education.

Hi Michel, could you please make a video on this viral age problem:
Mary is 24 years old. Mary is twice as old as Ann was when Mary was as old as Ann is now. How old is Ann?

Can you project the circumference of a circle onto a line that goes through the circle's origin and intercepts a tangent line or secant of that circle? (Similar to what you have depicted here)

weird.. i divided the 130/2 got 65.. 65-90=25 since we divided by 2 we multiply by 2 and get 50... I just drew a line from C to A creating 2 right triangles...
