So for this, we will be using tangent to solve (Remember that tangent = opposite/adjacent)
In this case, our equation is
For this, all you need to do is cross-multiply, and your answer will be
Answer:
Step-by-step explanation:
For this case we can use the figure attached and we are interested in order to find the value of x.
We have two similar triangles (DEC and ABC) and we can find the scale factor like this:
And now we can apply proportions in order to find the value of x using the two sides DE and BA, since we have the ratio between the triangle DEC and ABC we have this:
And solving for x we got:
And then the distance across the lake would be 2000 ft
