Answer: 11378.58 ft
Step-by-step explanation:
1. Draw a figure like the one attached, where A is the position of the airplane and B and C are the positions of the cars.
2. The distance between the cars is the length BC, then, you need to calculate the measure of BD and DC to add them and obtain BC.
<h2> 3. You know the opposite side and the angles of depression, then, you can calculate the distance between the cars as following:</h2>

Answer: v = 12
Step-by-step explanation:
R=4 because 20-4 = 16 and 4 times 4 = 16
The answer is 8 because four plus eight equals twelve
Answer:
C. Centroid
Step-by-step explanation:
The circumcenter is the center of a triangle's circumcircle (circumscribed circle over triangle). It can be found as the intersection of the perpendicular bisectors.
The incenter is the center of the incircle (inscribed circle into a triangle) of a triangle. The incenter can be constructed as the intersection of angle bisectors.
Centroid is the point where the three medians of the triangle intersect.
The intersection of the three altitudes of a triangle is called the orthocenter.
Since three medians intersect at point which divides each median into 2:1 ratio, the answer is centroid.
