The height of the statue is of 35 feet, applying similarity of triangles.
<h3>What are similar triangles?</h3>
Similar triangles are triangles that have congruent angle measures, thus the measures of their side lengths are proportional. This relation can be proven from the law of sines.
In the context of this problem, there are two similar right triangles, in which:
- Minh's height of 5 feet is proportional to the statue's height of x.
- The base formed by Minh's height, of 12 ft, is proportional to the base formed by the statue's height, of 84 ft.
Hence the following proportional relationship is established:
5/x = 12/84
Applying cross multiplication, it is found that:
12x = 84 x 5
Simplifying by 12, the expression is written as follows:
x = 7 x 5 (as 84/12 = 7).
x = 35 feet, which is the height of the statue.

Answer:
2.96 = 2 96/100 = 2 24/25
Answer:
-4x-6y=2x+6y
Step-by-step explanation:
Let his total money be x.
He spent (3/7)*x of his money.
He gave 1/4(x-3/7x) to his sister.
which is : (1/4)*(4/7)*x = (1/7)*x
Now,
How much money he have in the beginning =
(3/7)*x+(1/7)*x+120=x
(4/7)*x+120=x
120=x-(4/7)*x
120=(3/7)*x
x=120*7/3 [cross multiplication]
x=280.
So, Alex had $280 in the beginning.
So to do this one, you have to do the problem backwards!
The equation looks like this with everything plugged in:
272.2 = 2(3.14)r
You are looking for r, so start dividing
272.2 = 2(3.14)r
136.1 = (3.14)r
43.3 = r
Therefore the radius is about 43.3 in.
I hope I helped!
