A source of laser light sends rays AB and AC toward two opposite walls of a hall. The light rays strike the walls at points B and C, as shown below: What is the distance between the walls? a 110.90 m

b 149.28 m

c 103.92 m

d 173.20 m

Using the ratios of a 30 - 60 - 90 triangle we can find that the distance between the first wall and laser source is 20√3 and the distance between the second wall and the laser source is 40√3 so the distance between the walls us 20√3 + 40√3 = 60√3 = 103.92.
