Question

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:

A source of laser light is at point A on the ground between two parallel walls. The walls are perpendicular to the ground. AB is a ray of light which strikes the wall on the left at point B which is 60 meters above the ground. AC is a ray of light which strikes the wall on the right at point C which is 40 m above the ground. The ray AB makes an angle of 60 degrees with the ground. The ray AC makes an angle of 30 degrees with the ground.

Answer 1

C is the best choice

Answer 12

40cot(30∘)+60cot(60∘)=603√=103.923 i didnt want to give him the answer i wanted him to solve for it but yeah C

Answer 13

I got 103.923

Answer 14

Oh

Answer 15

In today's age they use graphing calculators for common core standard. He still understands it

Answer 16
