Answer:
reflection across the line y = x
Step-by-step explanation:
The orientation of the triangle has changed from CW to CCW (considering sides in order least-to-greatest). This means a reflection is involved.
In order for this to be a single transformation, we need to know the line or point of reflection.
Each point is reflected about the point that is the midpoint joining an image point and the corresponding preimage point. Here, the points of reflection of the vertices all lie on the line y = x. So we can say ...
the transform is reflection across the line y = x
Answer: 
Step-by-step explanation:
Observe the figure attached.
You can identify that the triangle formed is Isosceles, because it has two equal sides.
Notice that you can divide it into two equal right triangles. Now the angle 20° is divided by 2 and you get two equal angles that measure 10°.
To find "x", apply the Trigonometric Identity 
:
Then, the distance between the lighthouses can be represented with:
Substituting the value of "x" into this equation, you get:
