The angle of depression is 29.0521°. So it is a safe landing.

Step-by-step explanation:

Step 1:

The plane is flying at a height of 25,000 feet and 45,000 feet away from the landing strip. Assume it lands with an angle of depression of x°.

So a right-angled triangle can be formed using these measurements. The triangle's opposite side measures 25,000 feet while the adjacent side measures 45,000 feet. The angle of the triangle is x°.

To determine the value of x, we calculate the tan of the given triangle.

tanx = \frac{opposite side}{adjacent side}.

Step 2:

The length of the opposite side = 25,000 feet.

The length of the adjacent side = 45,000 feet.

tan x = \frac{25,000}{45,000} = 0.5555.

So x = 29.0521°. Since x < 30°, it is a safe landing.

Paladinen [302]
\text{Area of the triangle = 6 unit}^2Explanation:

The triangle is right angled.

The formula for area of the triangle:

\begin{gathered} A\text{ = }\frac{1}{2}bh \\  \\ b\text{ = base} \\ h\text{ = height} \end{gathered}

base = 3

height = 4

substitute the values:

\begin{gathered} \text{Area of the triangle = }\frac{1}{2}\times3\times4\text{ = 12/2} \\ \text{Area of the triangle = 6 unit}^2 \end{gathered}

First, drag a value to represent the missing angle in the triangle. Then, complete the trigonometry equality statements.
noname [10]

The missing trigonometric values are listed below:

  • Angle A = 90 - θ
  • sin 28°  =  cos (62°)
  • Cos 33°  =  sin 57°
  • Cos 31°  =  sin 59°
  • Cos (90 - θ) = sin(θ)

<h3>Meaning of Trigonometry</h3>

Trigonometry is a branch of mathematics that studies angles of triangles and its side length.

Trigonometry is so important that every student must come across this branch of mathematics.

In conclusion, the missing trigonometric values are listed above
