Aₙ = 7n+4
n = 12 thus
a₁₂ = 7(12) + 4
Answer:
(-1, 2) and (-1, 3.5)
Step-by-step explanation:
The triangle ΔDEF spans 4 squares horizontally.
So, the midsegment of ΔDEF will coincide with the line 4/2 = 2 squares from the vertex F.
Note that the <em>x </em>coordinate of the vertex F is -3 and 2 units to the right of F is -1.
Therefore, the midsegment of ΔDEF coincides with the line <em>x</em> = -1.
So, the <em>x</em> coordinates of the end points of the midsegment are -1.
Let's find the <em>y</em> coordinates of the end points.
From the given figure, it is clear that the mid point of FD is half way between 3 and 4 and hence it is 3.5.
Mid point of FE is 2.
So, the co-ordinates of the end points of the midsegment are (-1, 2) and (-1, 3.5).
