Answer:

Step-by-step explanation:

To calculate c from the first right angle triangle,

C2 = 36 + 16

C = sqrt(52)

To calculate a from the bigger right angle triangle,

B2 + 52 = (a + 4)2

B2 - a2 = -36 + 8a

A2 + 36 = B2

Solving both by elimination,

A = 72/8

Let $G$ be the center of equilateral triangle $XYZ.$ A dilation centered at $G$ with scale factor $-\frac{4}{3}$ is applied to t

umka2103 [35]

The area divided by XYZ is 16/9

i.e. $\frac{A}{[XYZ]} = \frac{16}{9}$

The given parameters can be represented as:

$r = -\frac{4}{3}$ --- the ratio of dilation

The area of the second triangle is as follows:

$A =r^2 * \triangle XYZ$

Make $r^2$ as subject

$r^2 = \frac{A}{\triangle XYZ}$

Substitute value for $r^2$

$(\frac{4}{3})^2 = \frac{A}{\triangle XYZ}$

$\frac{16}{9} = \frac{A}{\triangle XYZ}$

Rewrite as:

$\frac{A}{\triangle XYZ} = \frac{16}{9}$
