This is true because a reflection is a rigid transformation, which means it preserves shape size and angle measure
hope this helps!

kicyunya [14]

Let's call the height of the tower $h$ and the distance from the 65 degree angle to the base of the tower $d$ .

We get two equations:

$\tan 65^\circ = \dfrac h d$

$\tan 39^\circ = \dfrac{h}{d+37}$

$h = d \tan 65^\circ = (d+37) \tan 39^\circ$

$d(\tan 65 - \tan 39) = 37 \tan 39$

$d = \dfrac{37 \tan 39}{\tan 65 - \tan 39}$

$h = d \tan 65 = \dfrac{37 \tan 39 \tan 65}{\tan 65 - \tan 39}$

$h \approx 48.1 \textrm{ feet}$

Answer:

(d) (x² + y² + z²)³ = 27x²y²z²

Step-by-step explanation:

Use the identity:

a³ + b³ + c³ = 3abc if a + b + c = 0

Substitute as follows:

a = $x^{2/3}$ , b = $y^{2/3}$ , c = $z^{2/3}$

The sum of the cubes is:

x² + y² + z² = 3(xyz) $^{2/3}$

Cube both sides:

(x² + y² + z²)³ = 27x²y²z²

Correct choice is (d)
