Answer:

For first question answer is D.0.8

For second question answer is D.ΔMGR is similar to ΔNST.

Step-by-step explanation:

Here triangle FUN is dilated to get triangle PET

So, let's take F and P.

F(-2,4) and P(-1.6, 3.2)

Let's find the scale factor by dividing the coordinates.

Scale factor =[tex]\frac{-1.6}{-2} =0.8[/tex]

Using y coordinates of the same points

Scale factor =[tex]\frac{3.2}{4} =0.8[/tex]

So, scale factor is 0.8

Now, for the second problem

<G= <S

<R= <T

<M=<N

So, the corresponding angles are congruent when two triangles similar.

So, we can say ΔMGR is similar to ΔNST.
