Question

A piece of glass is placed between a flashlight and a piece of paper. The glass is 12

nches tall and is located 45 inches away from the wall and 15 inches away from
he flashlight. What is the length of the shadow that would be produced on the
wall?

Answer 1

To solve the problem, we can use similar triangles. Let x be the length of the shadow on the wall. Then we have:

x/45 = 12/15

Cross-multiplying, we get:

15x = 45 * 12

Simplifying, we get:

15x = 540

Dividing both sides by 15, we get:

x = 36

Therefore, the length of the shadow on the wall is 36 inches
