The altitude is 8.7 km
Step-by-step explanation:
The given scenario will form a right-angled triangle where the angle is 30 degrees.
The altitude will be the perpendicular of the triangle and the distance along its pathway will be the base so we have to find the altitude.
Let x be the altitude, then
[tex]tan\ 30 = \frac{x}{15}\\0.5773=\frac{x}{15}\\x =15*0.5773\\x= 8.6595[/tex]
Rounding off to nearest tenth
x = 8.7 km
Hence,
The altitude is 8.7 km
