The triangle is drawn and is shown in the image attached with.
We get two similar triangles. Triangle ABC and Triangle ADE. Since the triangles are similar the ratio of their corresponding sides will be the same.
D and E are the midpoints of AB and BC, therefore, AD and AE are both 4 units in length. Using the property of similar triangles, we can say:
AD : DE= AB : BC
AD = 4 units
AB = 8 units
BC = 6 units
DE = unknown = x units
So,

Therefore,
the length of DE will be 3 units
Step-by-step explanation:
I am not sure. sorry if it is wrong
Your answer will be A. (8,1)
You began to do the equation from left to right. 8-10 = -2, so -2+5= 3, 3+6= 9f
hence the answer is
quotient is X + 7 and remainder is 8
