The distance from tree 1 to tree 3 is about 205 meters.
An equation is an expression used to show the relationship between two or more variables and numbers.
Let a represent the distance from tree 1 to 2, b from 2 to 3 and c from tree 3 to 1.
Hence:
a + b = 335
Also:
b + c + a = 540
a + b + c = 540
335 + c = 540
c = 205 meters
