Answer:

Angle DAB is congruent to Angle CAE by Vertical Angle Theorem

2x+6=96 by Vertical Angle Theorem.

Step-by-step explanation:

Vertical Angles are angles which are across from each other but share a vertex. These angles are always congruent and can be proven by reflection. In the figure, angles DAB and CAE are congruent. Angles DAC and BAE are also congruent.

We can solve for unknown angles using VErtical Angle Theorem by setting them equal and isolating x. To create a proof begin with what is given, followed by the VA theorem and then continue on to solve for x.

A. 530 ft^2<br><br> B. 500 ft^2<br><br> C. 470 ft^2<br><br> D. 450 ft^2

Answer: OPTION A.

Step-by-step explanation:

Find the length scale factor by dividing the known length of the larger triangle by the known length of the smaller triangle:

$lenght\ scale\ factor=\frac{35}{25}=\frac{7}{5}$

Then, the area scale factor is:

$area\ scale\ factor=(\frac{7}{5})^2=\frac{49}{25}$

To find the area of the the larger triangle, multiply the area of the smaller triangle by the area scale factor. Then:

$A_{(larger)}=(270ft^2)(\frac{49}{25})=529.2ft^2$

So, the option that shows an approximation of the area of the larger triangle is the option A:

$A_{(larger)}$ ≈ $530ft^2$
