Answer:

Step-by-step explanation:

Plate tectonics is a scientific theory describing the large-scale motion of the plates making up the Earth's lithosphere since tectonic processes began on Earth between 3.3 and 3.5 billion years ago. The model builds on the concept of continental drift, an idea developed during the first decades of the 20th century.

Answer:

Distance between the school and the theater = $2\sqrt{13}$ units

Step-by-step explanation:

Use distance formula to calculate the distance from the school (8, 7) and the theater (2, 3):

$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Let,

$school (8, 7) = (x_1, y_1)$

$theater (2, 3) = (x_2, y_2)$

Plug in the values into the distance formula

$d = \sqrt{(2 - 8)^2 + (3 - 7)^2}$

$d = \sqrt{(-6)^2 + (-4)^2}$

$d = \sqrt{36 + 16} = \sqrt{52}$

Simplify

$d = \sqrt{4 \times 13}$

$d = 2\sqrt{13}$

Consider the first term on the left side.

$\displaystyle \frac{2\sin{A}}{\cos{3A}}\\\\=\frac{2\sin{A}\cos{A}}{\cos{3A}\cos{A}}\qquad\text{multiply by cos(A)/cos(A)}\\\\=\frac{\sin{2A}}{\cos{3A}\cos{A}}\qquad\text{double angle formula for sin}\\\\=\frac{\sin{(2A-A)}}{\cos{3A}\cos{A}}=\frac{\sin{3A}\cos{A}-\cos{3A}\sin{A}}{\cos{3A}\cos{A}}\\\\=\tan{3A}-\tan{A}$

Then the sum of the three terms on the left is

$\left(\tan{3A}-\tan{A}\right)+\left(\tan{9A}-\tan{3A}\right)+\left(\tan{27A}-\tan{9A}\right)\\\\=\tan{27A}-\tan{A}\qquad\text{Q.E.D.}$
