Question

1) A 15 foot flagpole casts an 11 foot shadow. At the exact same time a 28 foot tree casts a shadow. Which proportion would correctly find the length of the tree's shadow? A) x 28 = 11 15 B) x 28 = 15 11 C) 28 x = 11 15 D) x 15 = 11 28

Answer 1

D

Explanation:

Answer 2

D

The model involves similar triangles with the ratios of corresponding sides being equal

let x be the length of the tree's shadow, then

`(28)/(15)` =
`(x)/(11)` ( cross- multiply )

15x = 11 × 28
