Answer:


Step-by-step explanation:
Trapezoid ABCD is isosceles trapezoid, because AB = CD (given). In isosceles trapezoid, angles adjacent to the bases are congruent, then
Since BK ⊥ AD, the triangle ABK is right triangle. In this triangle, AB = 8, AK = 4. Note that the hypotenuse AB is twice the leg AK:
If in the right triangle the hypotenuse is twice the leg, then the angle opposite to this leg is 30°, so,

Since BK ⊥ AD, then BK ⊥ BC and

Thus,

Now,

<em> $ 44616</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>What will be the price of the next model ?</em>
<em>$39000 + $39000×14.4% =</em>
<em>= $39000 + $39000×0.144</em>
<em>= $39000(1 + 0.144)</em>
<em>= $39000×1.144</em>
<em>= $ 44616</em>
<em>Good luck !</em>
