ABC is isosceles with AB=AC=8 units and BC=6 units. D and E are midpoints of AB and BC respectively. Calculate the length of DE?
Allushta [10]
The triangle is drawn and is shown in the image attached with.

We get two similar triangles. Triangle ABC and Triangle ADE. Since the triangles are similar the ratio of their corresponding sides will be the same. 

D and E are the midpoints of AB and BC, therefore, AD and AE are both 4 units in length. Using the property of similar triangles, we can say:

AD : DE= AB : BC
AD = 4 units
AB = 8 units
BC = 6 units
DE = unknown = x units

So,

4 :x = 8 : 6 \\  \\ 
 \frac{4}{x} = \frac{8}{6}  \\  \\ 
x=4* \frac{6}{8}=3 


Therefore, the length of DE will be 3 units

Compute the radius of the largest circle that is internally tangent to the ellipse at $(3,0),$ and intersects the ellipse only a
Artyom0805 [142]

Answer: radius of the largest circle is Zero.

Step-by-step explanation: A circle can't fit into an ellipse with such coordinate (3,0). What that coordinate means is that the ellipse lies along the x axis 3unit from the origin along the x axis and 0 unit from the origin along the y axis. At which no circle can fit in.

Moreso, the the coordinates at which the circle intercepts the ellipse as to be uniform not (3,0).

A circle as a constant radii coordinate on both axis.

I believe you can now see why my answer is Zero.
