Think of the right triangle formed by the ladder, the height of the upper end of the ladder and the distance of the bottom of the ladder from the wall.

Then x = 6 ft and the hyp is 10 ft.  The trig function cos theta  equals "adj side" / hyp, so, in this case,

cos theta = 6/10 = 0.6.  Use the arccos x function on your calculator to find the angle x:

x = 0.927 (radians) = 53.1 degrees.

The federal tax code allows some items used for business purposes to be depreciated. That is, their taxable value decreases over
Phantasy [73]

Answer: T = 22,000 - 1,900n

Step-by-step explanation:

Taxable value is $22,000

The tax code allows for the depreciation of this van by $1,900 per year.

After n years therefore the total depreciation is;

= 1,900 * n

This depreciation will need to be removed from the taxable value of $22,000 to find out the taxable value left.

Formula is therefore;

T = 22,000 - 1,900n
