Answer: x =8

Step-by-step explanation:

-12 + 9x = 60 (the other angles are 60, 180 - (60 + 60) = 60)

9x = 72

x = 8

Answer:

x = 8°

Step-by-step explanation:

We know that sum of interior angles of a triangle is 180°, therefore;

<em>(Angle 1) + (Angle 2) + (Angle 3) = 180°</em>

(60)° + (60)° + (-12 + 9x)° = 180°

120° + (-12 + 9x) = 180°

108° + 9x° = 180°

9x = 180 - 108

9x = 72°

x = 72/9

x = 8°

Therefore the <u>value of x is 8°.</u>

Hope this helps!

The distance BC from Tower 2 to the plane will be 14,065.5 ft and the height of the plane from the ground will be 5,720.9 ft.

<h3>What is a right-angle triangle?</h3>

It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.

A plane is located at C on the diagram.

There are two towers located at A and B.

The distance between the towers is 7600 feet and angles of elevation are given.

Then in the right-angle triangle ΔADC, we have

\rm \tan 16 = \dfrac{H}{7600 + X}\\\\\\H = 0.2867(7600 +X)\\\\\\H = 0.2756\ X + 2179.2649 ...1

Then in the right-angle triangle ΔBDC, we have

\rm \tan24 = \dfrac{H}{ X}\\\\\\H = 0.4452\ X ...2

From equations 1 and 2, we have

0.4452X = 0.2756 X + 2179.2649

0.1696X = 2179.2649

            X = 12849.439 ≅ 12,849.4 ft

Then the distance BC from Tower 2 to the plane will be

\rm BC = \dfrac{12849.4}{\cos 24}\\\\\\BC = 14065.5 \ ft

Then the height of the plane from the ground will be

\rm H = 12849.4 \times  \tan 24 \\\\\\H = 5720.9 \ ft

The figure is shown below.

More about the right-angle triangle link is given below.
