Answer:

Step-by-step explanation:

This is a problem of similar triangles solved using proportions.

In similar triangles, corresponding side lengths are proportional.

Here the small and large triangles are similar because the have all three angles congruent.

By proportions, identifying corresponding sides,

solve for x

x = 45*(50/30) = 75 m

The area of a square photo is 9 square inches how long is each side of the photo

Marta_Voda [28]

Let the side of each side of photo is a inch.

So area of photo = (side)^2 = $a^2$

But as given area of photo is 9 square inch.

So $a^2 = 9$

$a = \sqrt{9}$
$= 3$

So side of photo is 3 inch.

Answer:

n < 27

Step-by-step explanation:

let the number be n

$\frac{1}{3} n - 3 < 6 \\ add \: 3 \: to \: both \: sides \\ \frac{1}{3}n - 3 + 3 < 6 + 3 \\ \frac{1}{3} n < \\ 9 \\ multiply \: both \: sides \: by \: 3 \\ \frac{1}{3} n \times 3< 9 \times 3 \\ n < 27$
