Answer:
6.06 km
Step-by-step explanation:
The information given in the question can be represented by the three sides if a right angled triangle.
Let the direct line from the airplane to the start of the runway be represented by x. So that applying the appropriate trigonometric function, we have;
Cos θ =
Cos =
0.9903 =
⇒ x =
= 6.0588
x = 6.06 km
The direct line from the airplane to the stat of the runway is 6.06 km.
There exists the same question from other source that has the image of the drawing. Attached to this answer is the image.
To solve this, first we have to assume ratios.
Real Height / Shadow = 56 / 49
Real Height / 28 = 56 / 49
49 * h = 56 * 28
49h = 1568
Then, we have to divide both sides by 9
h = 32
Therefore, the obelisk is 32 ft
