Answer:
x = 4.5
Step-by-step explanation:
6x+7=4x+4y
The first step is to simplify the equation by combining the x terms
Subtract 4x from each side
6x-4x +7 = 4x-4x+4y
2x+7 = 4y
We know the y value is 4
Substitute y=4 into the equation
2x+7 = 4(4)
2x+7 =16
Subtract 7 from each side
2x+7-7 =16-7
2x=9
Divide by 2
2x/2 =9/2
x= 4.5
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.
