Answer:

  • The mirror is 20/3 of feet, which is about 6.7 feet, from the basketball goal.

Explanation:

The figure attached represents the situation.

The triangle on the left and the triangle on the right are similar triangles because they are right triangles and the marked angles are congruent.

The distance between the mirror and the basketball goal is represented by the unknown x.

By similarity:

  • [tex]10/6=x/4[/tex]

Solving:

  • [tex]x=40\times 10/6=40/6=20/3[/tex]

Thus, the mirror is 20/3 of feet, which is about 6.7 feet, from the basketball goal.
