Short Answer Question 1: A hiker on one side of a river at point A sees a tent on the other shore of the river at point C. The angle at A (angle DAC) is determined to be 65 o. The hiker walks 100 feet along the edge of the river to point B and sees the tent again, and determines the angle at B (angle DBC) to be 20 o. Use this information to determine the straight-line distance directly across the river from point D to point C. Note: This is the width of the river at point C. Round your answer to 1 decimal place.

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.
