Answer:

80 m

Step-by-step explanation:

The described points form two right triangles which share same horizontal leg a.

The bottom triangle has 60 m vertical length and 60° opposite angle.

The triangle on the top has unknown (x) vertical length and 30° opposite angle.

We are looking for the distance x + 60 m

On the top triangle we have:

tan 30° = x/a ⇒ a = tan 30° / x

On the bottom triangle we have:

tan 60° = 60/a ⇒ a = tan 60° / 60

Comparing we get:

tan 30° / x = tan 60° / 60
x = 60 tan 30° / tan 60°
x = 20 m

So the distance is:

60 m + 20 m = 80 m
