Answer:
10
Step-by-step explanation:
To find the value of x, create a proportion. A proportion is two equal ratios for similar figures. The two triangles are similar because they are the same shape but not the same size. Create ratios between corresponding sides of figures.
To solve for x, cross multiply:
12(x+4) = (2x+1)(8)
12x + 48 = 16x + 8
48 = 4x + 8
40 = 4x
10 = x

<h2>Explanation:</h2>
The stairway to a cellar has a slope of -4/3, that is:
On the other hand, the cellar is 2m below the ground. In other words:
So this can be modeled by the equation of the line:
The line has a y-intercept at point (0, -2) and as x increases 3 units y decreases 4 units. So:
Finally, let's draw a line that passes through:
By using graphing tool, we get the line shown below.
