What are the coordinates of N?

Nataliya [291]

Answer:

$(c,b) are the coordinates of N$

Step-by-step explanation:

as N is the mid-point of QR

BY USING MID-POINT FORMULA

$N(x,y)=(\frac{x1+x2}{2},\frac{y1+y2}{2})$

PUTTING THE VALUES OF COORDINATES

$N(x,y)=(\frac{0+2c}{2},\frac{2b+0}{2})$

$N(x,y)=(\frac{2c}{2},\frac{2b}{2})$

$N(x,y)=(c,b) are the coordinates$

O HOPE THIS WILL HELP YOU :)

What is the value of x in the diagram below? If necessary, round your answer

dexar [7]

Answer:

$\text{C. }7.2$

Step-by-step explanation:

In the figure, all three triangles are similar. By definition, the corresponding sides of similar polygons must be in a constant proportion. Therefore, we can set up the following proportion to solve for $x$ by dividing corresponding sides:

$\frac{x}{12}=\frac{12}{20},\\20x=144,\\x=\frac{144}{20}=\boxed{\text{C. }7.2}$
