The two angles form a straight line which is equal to 180 degrees. This makes the angles supplemtary.
To find x, add the two angles together to equal 180:
7x + x+20 = 180
Combine like terms:
8x + 20 = 180
Subtract 20 from both sides:
8x = 160
Divide both sides by 8:
X = 20
Divide the number of blocks by number of people
In this case 5/6 = 0.83 blocks or each person will get 0.83 or 5/6 of a block
That is the centroid.
The point where the lines from each vertex of the triangle to the midpoints of the opposite sides intersect.
