The answers of the product is 1.8 * 0.63 = 1.134
The value would be $14,000.
The formula we use for this is
A = p(1+r)ˣ, where p is the initial value, r is the percent of depreciation (as a decimal number) and x is the number of years. Note that since it is depreciation, r will be a negative number.
A = 25000(1-0.08)⁷ = 13946.17 ≈ 14000
A single angle is generally not considered to be supplementary. Supplementary angles are angles that equal 180° when they are added together. For example, 70° and 110° are supplementary because they equal 180°.
However, I guess the supplementary angle can be the angle that must be added to another to total 180°. For example, 80° is the supplementary angle of 100°.
