Answer:
The coordinates of the mid-point of JL are (-5 , 2)
Step-by-step explanation:
If point (x , y) is the mid-point of a segment whose end-points are and
, then
and
∵ JL is a segment
∵ The coordinates of J are (-6 , 1)
∴ = -6 and
= 1
∵ The coordinates of L are (-4 , 3)
∴ = -4 and
= 3
Lets use the rule above to find the mid-point of JL
∵
∴ x = -5
∴ The x-coordinate of the mid-point is -5
∵
∴ y = 2
∴ The y-coordinate of the mid-point is 2
∴ The coordinates of the mid-point of JL are (-5 , 2)
The first two rows of coefficients are identical, so by inspection, the determinant is 0.
The side opposite to angle B is the side that does not contact with angle B.
In this attached image, you can see better that sides AB and BC is in contact with angle B. So, the opposite side to angle B is AC.
Therefore, the lenght of the side opposite to angle B is 4 units.
