Find the other endpoint of the line segment with the given endpoint and midpoint. Endpoint: (4,-9)
Midpoint: (10,8)

Other Endpoint (x₂,y₂) = (16,25)

Step-by-step explanation:

We are given endpoint = (4,-9) and midpoint(10,8) we need to find the other endpoint of line segment.

Let other endpoint be (x₂,y₂)

The formula used to find other endpoint is using formula of midpoint

We have

Using formula and finding (x₂,y₂)

So, x₂=16 and  y₂=25.

So, Other Endpoint (x₂,y₂) = (16,25)

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
