PLEASE HELP
Aloiza [94]
  • Volume=2.7million km^3
  • Base=339milliom km^2

\\ \tt\longmapsto Volume=Base\times Height

\\ \tt\longmapsto Height=\dfrac{Volume}{Base}

\\ \tt\longmapsto Height=\dfrac{2.9km^3}{339km^2}

\\ \tt\longmapsto Height=0.00079km

\\ \tt\longmapsto Height=7.9m

A plane is flying 3900 m above the ground level. The angle of elevation from the control tower to the plane is
Tcecarenko [31]

The horizontal distance to the control tower is approximately 18506.83m

Data;

  • distance from the ground = 3900m
  • angle of elevation = 11.4 degrees
  • horizontal distance = ?

<h3>Trigonometric Ratio</h3>

To solve this problem, we need to use trigonometric ratio SOHCAHTOA.

In this case, we have the value of opposite and angle and we need to find the adjacent to the angle. The tangent of the angle would be perfect for this.

tan\theta = \frac{opposite}{adjacent} \\tan11.4 = \frac{3900}{x}\\x = \frac{3900}{tan11.4}\\ x = 18506.83m

The horizontal distance to the control tower is approximately 18506.83m
