Explanation

Since the sum of the angles in a triangle is always 180 degrees, and two of the angles are already 60 degrees each, the third angle can be found by subtracting the sum of the two known angles from 180:

So, the third angle is also 60 degrees, making the triangle an equilateral triangle.

Explanation

Since there are 8 mango trees, and the distance between each tree is 3 meters, the total distance between the first tree and the eighth tree would be:
