A boat is anchored offshore. From the bow of the boat, 39ft of anchor line is out with 4ftof line above the water. The angle that the line makes with the water line is 21°
a= 4ft B=21
.
The water is approximately
deep.
Figure in plane geometry formed by two rays or lines that share a common endpoint, called the vertex. The angle is measured in degrees using a protractor. The different types of angles are acute, obtuse, right, straight, and reflex.
