ok

Answer 2

thank you

If quadrilateral BDMZ is a rhombus, which of the following ordered pairs could be a vertex?


(-9, 3)

(-10, 3)

(-10, 4)

(-9, 4)

Answer 3

since all four sides of rhombus of are congruent.so find the distance of BD using distance formula
\[\Large d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\]
\[\Large d=\sqrt{(-2-(-5))^2+(1-5)^2}=\sqrt{(3)^2+(-5)^2}=\sqrt{34}\]
now find the distance of points given above from both either D or B
for the point whose distance is \[\sqrt{34}\]
is the required point.
i am finding the distance between point B and (-9,3)
\[\Large d=\sqrt{(-9-(-5))^2+(3-6)^2}=\sqrt{(-4)^2+(-3)^2}=\sqrt{25}=5\]
SO (-9,3) IS NOT THE POINT
now find the distances from point B for the point whose distance will be \[\sqrt(34)\]
is the required point!

Answer 4

@diva15 can you find it now ?

Answer 5

(-9, 4)

Answer 6

????

Answer 7

nopes! try again.

Answer 8

then it got to 2 be (-10,3)

Answer 9

you got it this is correct :)
