Answer:
The value of h is 42.956 approximately.
Step-by-step explanation:
Consider the provided formula
Here d is the distance of the driver from the letters and e is the height of the driver's eye above the pavement. All of the distances are in meters.
We need to find the value of h where the value of d = 92.4 m, e = 1.7 m.
Substitute d = 92.4 m, e = 1.7 m in above formula and solve for h.
Hence, the value of h is 42.956 approximately.
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.
Step 2:
The length of the opposite side = 25,000 feet.
The length of the adjacent side = 45,000 feet.
So x = 29.0521°. Since x < 30°, it is a safe landing.
