The diagonals of a rhombus intersect at the point (0,4). if one endpoint of the longer diagonal is located at point (4,10), where is the other endpoint located?

The other endpoint is located at (-4,-2)

Step-by-step explanation:

we know that

The diagonals of a rhombus bisect each other

That means-----> The diagonals of a rhombus intersect at the midpoint of each diagonal

so

The point (0,4) is the midpoint of the two diagonals

The formula to calculate the midpoint between two points is equal to

we have

substitute

Find the x-coordinate of the other endpoint

Find the y-coordinate of the other endpoint

therefore

The other endpoint is located at (-4,-2)

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

unless if u could do my questions, if not i wouldn't want to
