Answer:

Step-by-step explanation:

By definition, CD is an angle bisector.  What that does is creates proportionality between the sides of each respective triangle.  Here's the proportion:

\frac{4}{3} =\frac{7.5}{x}

Cross multiply to get 4x = 22.5  and

x = 5.625

The base of an auditorium is in the form of an eclipse 200 feet long and 100 feet wide a pin drop near one focus can clearly be
dedylja [7]

Answer:

Let the coordinate of focus be (\pm c , 0)

As per the statement: The base of an auditorium is in the form of an eclipse 200 feet long and 100 feet wide.

⇒Length of Major axis=base of an auditorium = 200 feet and Length of a minor axis=wide of a auditorium = 100 ft

Semi-major axis (a) = 100 ft and

semi-minor axis(b) = 50 ft

Then, by an equation:

c^2 = a^2-b^2

Solve for c:

Substitute the given values we have;

c^2=(100)^2-(50)^2

Simplify:

c^2 = 7500

or

c=\sqrt{7500} = 86.6025404 ft

Distance between the foci is,  2c = 2 \cdot 86.6025404 = 173.205081

Therefore, the distance between the foci to the nearest 10th of a foot is, 173.2 ft
