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.

Hi there!
Since we know that 36 is 1/10 of 360, all we need to do is divide the total area (85) by 10. This gives us 8.5pi ft^2.
Hope this helps!! :)
