I would like to know how to do this question. I was thinking I could make one big triangle with the lengths I was given, but I'm not sure. Any help is appreciated.

You are installing an infrared security scanning device in the comer of a living room 8 inches below the
ceiling. You need to set the scan angle on the scanning device so that it will scan from one corner of the
room to the opposite corner of the room. The room measures 20 feet long, 12 feet wide and is 10 feet tall.
It is your job to figure out the angle 0 that the device should be set to scan.

Polygon with three sides, three angles, and three vertices. Based on the properties of each side, the types of triangles are scalene (triangle with three three different lengths and three different angles), isosceles (angle with two equal sides and two equal angles), and equilateral (three equal sides and three angles of 60°). The types of angles are acute (less than 90°); obtuse (greater than 90°); and right (90°).

Expert Solution

Step 1

To determine the angle that the camera should scan.
