4 and 8 would be the anwser because 4 x 2 = 8 and then 8x1=8
Answer:
midpoint of AB = (-1/2 , 0)
Step-by-step explanation:
A(-2 , 1) = (x1 , y1)
B(1 , -1) = (x2 , y2)
midpoint formula:
=(x1 + x2/2 , y1 + y2/2)
=(-2 + 1/2 , 1 + (-1)/2)
=(-1/2 , 0/2)
(-1/2 , 0)

Hello! Remember you have to write complete questions in order to get good and exact answers. I'll assume that you have a circle X having two tangent lines that intersect at a point outside the circle. From geometry, we know that from any point outside a circle, two tangents to that circle are always congruent to each other if they meet at the mentioned point. So if the point of intersection is called Z, and a line is tangent to the circle at a point Y, ZY must be equal to ZW because ZW is tangent to the same circle at point W and meets ZY at a point outside the circle, then it is true that:

So <em>the ZY must be equal 3 in order for ZY to be tangent to circle X at point Y</em>
