If you have a unit circle, it means that you have a circle of radius r = 1 unit. So if we consider the scalene triangle of the figure, its vertical side is the sine of the theta angle and its horizontal side is the cosine of the theta angle. Then to find the hypotenuse of the triangle you use the Pythagorean theorem, thus relating the sine and cosine measures. I attach the solution.
Answer:
Vertically opposite angles
Step-by-step explanation:
Given

What else can measure
The question has missing options. So, I will give a general explanation.
Using the attached image as a point of reference.
Given that:
The value of b is calculated as:
Because b and are vertically opposite angles
<em>This gives:</em>
<em></em><em></em>
<em></em>
<em>So, one possible answer to the question is a vertically opposite angle</em>
