Answer:
The pink angle is half the angle subtended by the blue arc.
Step-by-step explanation:
Given
See attachment for circle
Required
Compare the pink angle to the blue arc
Let the pink angle be x and the angle subtended by the blue arc be y.
So, we have:
[tex]x \to[/tex] angle at circumference
[tex]y \to[/tex] angle subtended by arc
The relationship between x and y is:
[tex]y =2x[/tex]
Make x the subject
[tex]x = \frac{1}{2}y[/tex]
