Answer:
Step-by-step explanation:
Let the coordinates of point B are (x, y).
Since the rotation is clockwise the angle measure between OA and OB is -60° (IV quadrant).
- x = 15 cos (-60°) = 7.5
- y = 15 sin (-60°) = -12.99
<u>The distance between A and B is:</u>
- AB = = 15 units
<h3><u>Another solution</u></h3>
Since OA = OB = 15 units and AOB is 60° angle the triangle OAB is equilateral. Hence AB is same as OA and OB, so AB = 15 units.
