This falls under geometry. The two labeled angles are congruent, which means the line segment between them (AD in the image) is a bisector of the angle at vertex A. Use the angle bisector theorem, which says that

\dfrac{BD}{DC}=\dfrac{AB}{AC}\iff\dfrac{12}{(5+9x)-12}=\dfrac{15}{25}

\dfrac{12}{9x-7}=\dfrac35

20=9x-7

x=3

A new car is purchased for 19700 dollars. The value of the car depreciates at
Usimov [2.4K]

Answer:

Step-by-step explanation:

We can plug this into a formula and get

5,500 = 19,700(.9075)^{?}

the .9075 comes from 1 - the depreciation value of 9.25% which converts to .0925 in decimal form.

? is what we are trying to solve for.

We can divide both sides by 19,700 and we get

\frac{55}{197} = (0.9075)^?

so ? is about 13.
