Derek sees that a 20 foot flagpole casts a 10 foot shadow. At the same time of day, if a nearby tree casts a 25 foot shadow, about how tall is the tree?

The height of the tree is 50 feet.

Step-by-step explanation:

Consider the provided information.

It is given that a 20 foot flagpole casts a 10 foot shadow. At the same time of day, if a nearby tree casts a 25 foot shadow.

Let the height of the tree is .

The flagpole and its shadow and tree and its shadow form similar triangles.

We know that the corresponding sides are in proportion in similar triangles.

Hence, the height of the tree is 50 feet.

a) what number, when added to negative four, is equal to negative five?

step-by-step explanation:

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
