Answer:
20.833 feet
Step-by-step explanation:
The light reflects off the mirror at the same angle that it hits it at. So the triangle formed by the beam and mirror is similar to the triangle formed by Kevin and the mirror.
Therefore, we can write and solve a proportion.
h / 10 = 6.25 / 3
h = 20.833
The beam is 20.833 feet tall.
I'm not really sure what I'm looking at... is it possible for you to take a better picture so I can look at the diagram if there is one + the rest of the steps?
-500 me cause that is the action that is being take place, it decreased by 500
Lower case numbers for points
7x +2y =-17 ..... Finally, answer
2x + 3y = -5
+
5x -y = -12
---------------------------
7x +2y = -17
