-x + 8 = x - 10
8 - x = x - 10
8 = x - 10 + x
8 = 2x - 10
8 + 10 = 2x
18 = 2x
18/2 = x
9 = x
x = 9

To evaluate ab - 0.50, we want to plug in the given values for a and b and then solve.
(1)(5)-0.5 [multiply]
5-0.5 [subtract]
4.5
After plugging in the values of a and b, we found that the solution is 4.5.
Answer:
The angle of depression calculator. How to find the angle of depression?
Since we now know what the angle of depression is, let's learn how to find it! We can determine the angle of depression using surveying equipment like an engineer's transit or a clinometer. These devices are optical instruments that have angle-measurement features and can instantly give us the angle that we need. However, we can also use mathematics to find the angle of depression. But first, we need to know two distances: the horizontal distance between the viewer and the object, and their vertical distance, as shown in the illustration below:
