1 answer:
The horizontal distance is 11.25 meters.
Step-by-step explanation:
Step 1:
The gradient of the given road is . The gradient is the ratio of the difference in y values to the difference in x values.
In the given diagram, the difference in y values is given as 3 meters.
The difference in x values is given as x meters.
So if we substitute it with the gradient, we can determine the values of x.
Step 2:
The gradient, by cross-multiplying we get
So the horizontal distance is 11.25 meters.

Answer:
11.4
Step-by-step explanation:
So we know that Triangle ACB is similar to Triangle EFD.
This means that their sides are proportional to each other.
We want to find x or side AB. To do so, we can set up a proportion.
The proportional side to AB is ED. Let's also use BC since we know its value. The proportional side to BC is DF. Thus:
Substitute x for AB, 3.8 for Ed, 15 for BC, and 5 for DF. Thus:
Reduce the right:
Cross multiply:
So, the value of x is 11.4
And we're done!
