Step-by-step explanation:

$c(n) = \frac{4}{9} ( - 3)^{n - 1} \\ \\ \therefore \: c(3) = \frac{4}{9} ( - 3)^{3- 1} \\ \\ \therefore \: c(3) = \frac{4}{9} ( - 3)^{2} \\ \\ \therefore \: c(3) = \frac{4}{9} \times 9 \\ \\ \huge{ \purple{ \boxed{\therefore \: c(3) = 4}}}$

Shaun drew ΔLMN, in which m∠LMN = 90°. He then drew ΔPQR, which was a dilation of ΔLMN by a scale factor of 3 from the center of

ioda

Answer:

The correct option is:

m∠R ≅ m∠N; this can be confirmed by translating point R to point N.

Step-by-step explanation:

ΔPQR, is a dilation of ΔLMN by a scale factor of 3 from the center of dilation at point M.

Which mean that the point M overlap the point Q, the point L translated to the point P and the point N to the the point R

So, ∠M=∠Q , ∠L=∠P , ∠N=∠R

And we should know that the dilation of triangles makes it similar.

And AA similarity postulate mean : the triangle will be similar when two pairs of corresponding angles are equal.

So, the correct answer will be the fourth option

m∠R ≅ m∠N; this can be confirmed by translating point R to point N.
