Answer:

a dilation and translation

Step-by-step explanation:

we know its a dilation because the lines of congruency are in the same area but the triangles are of different sizes

we know it's a translation because the triangles are in two different places instead of having something overlap

< ADF measures 2x degrees and < FDC measures x + 12 degrees. What is the measure

gtnhenbr [62]

Answer:

<h2>Angle ADF is equal to 52° and angle FDC is equal to 38°.</h2>

Step-by-step explanation:

In the image attaches, you can observe that angles ADF and FDC are complementary angles, because they sum 90°.

$\angle ADF + \angle FDC = 90\°$

And we know that

$\angle ADF=2x\\\angle FDC = x+12$

Replacing these expressions, we have

$2x+x+12=90\°\\3x=90\° - 12\°\\x=\frac{78}{3}\\ x=26$

Then, we replace this value in each expression to find both angles measures.

$\angle ADF= 2(26)=52\°\\\angle FDC = 26+12=38\°$

Therefore, angle ADF is equal to 52° and angle FDC is equal to 38°.

witch rule can you use to find the nth term of an arithmetic sequence in witch the common difference is 5 and a12=63

rewona [7]

Any arithmetic sequence can be expressed as:

a(n)=a+d(n-1), a=initial term, d=common difference, n=term number

We are only told that d=5 and a(12)=63 so:

53=a+5(12-1)

53=a+60-5

53=a+55

a=-2 now we have solved for a and we can say:

a(n)=-2+5(n-1) which neatened up....

a(n)=-2+5n-5

a(n)=5n-7

The above is the rule to find the value of the nth term.
