Find the difference of the two given angles

Answer to Problem 73E
Explanation of Solution
Given: Two angles
Concept Used:
Formally, the number being subtracted is known as the subtrahend, while the number it is subtracted from is the minuend. The result is the difference.
We can write: minuend - subtrahend = difference.
For subtraction we can use the formulas:
Calculation:
We know that Difference::
Thus, the difference of two angles

- A 20 foot ladder rests on level ground; its head (top) is against a vertical wall. The bottom of the ladder begins by being 12 feet from the wall but begins moving away at the rate of 0.1 feet per second. At what rate is the top of the ladder slipping down the wall?
