Step-by-step explanation:
we know that
The <u><em>Midpoint Theorem</em></u> says that the line segment joining the midpoints of any two sides of a triangle is parallel to the third side and equal to half of the third side
so
in this problem
Applying the midpoint theorem

Each ton is equal to 2,000 pounds, therefore each ton (12) times the number of pounds per ton (2,000) is 24,000 pounds! Hope this helps!!
In order for two lines to be perpendicular, their gradients must multiply together to get -1
7*b=-1
7b=-1
Divide both sides by 7
So, the gradient of line b is -1/7
