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.
Answer:
5.5 cm
Step-by-step explanation:
We are given that
Total number of chain links=1000
Length of chain=0.055 km
We have to find the length of a single chain link in cm.
Length of chain=m
1 km=1000 m
Length of chain=
1 m=100 cm
Length of single chain link=
Length of single chain link=5.5 cm
Hence, the length of single chain link=5.5 cm
