Answer:
PR = 8
Step-by-step explanation:
The median bisects the side opposite the vertex, so ...
P is the midpoint of AC
Since AC = 25, the length of half that segment is PC = 12.5. Of course, that is the sum of segments PR and RC:
PR + RC + PC
PR + 4.5 = 12.5 . . . . . fill in the known values
PR = 8 . . . . . . . . . . . . .subtract 4.5
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.
