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.) 80 m
b.) 180 m
c.) 90 m
d.) 100 m

OPTION D

Step-by-step explanation:

Both triangles are right triangles. Therefore, you can calculate the distance  between the walls as following:

- Calculate the adjcent side of the smaller triangle, which is distance from the wall to A (call this distance ), as following:

-  Calculate the adjcent side of the bigger triangle, which is distance from the wall to A (call this distance ), as following:

Then the distance  between the walls is:
