Your question is very unclear: how many years have past/months? If it's just how kuch it's depeeciated in one year the the answer would be 28,000•.25=7000 thus in one year the car is worth 7000$ less each year

please help with maths work
prisoha [69]

Given:

In a right angle triangle ABC, \angle B=90^\circ,x=8.7\ m, and \theta = 45^\circ

To find:

The value of AC.

Solution:

In a right angle triangle,

\cos \theta =\dfrac{Adjacent}{Hypotenuse}

\cos \theta =\dfrac{BC}{AC}

\cos (45^\circ) =\dfrac{8.7}{AC}

\dfrac{1}{\sqrt{2}}=\dfrac{8.7}{AC}

On cross multiplication, we get

AC=8.7\times \sqrt{2}

AC=12.30365799

AC\approx 12.304

Therefore, the measure of AC is 12.304 m.
