D(D,E) = 4.12 units.
d(F,G) = 5.39 units.
d(J,K) = 5 units.
d(L,M) = 4.242640687 units =4.24 units.
I hope it helps you.
C, because it says ABOVE 25,000 feet :)
Answer:

Step-by-step explanation:
AK is angle A bisector, then

BL is angle B bisector, then

Consider triangle ABL. The sum of the measures of all interior angles in this triangle is
then

Consider triangle ABK. In this triangle,
![m\angle AKB=180^{\circ}-2x^{\circ} \ [\text{Supplementary angles}]](https://tex.z-dn.net/?f=m%5Cangle%20AKB%3D180%5E%7B%5Ccirc%7D-2x%5E%7B%5Ccirc%7D%20%5C%20%5B%5Ctext%7BSupplementary%20angles%7D%5D)
The sum of the measures of all interior angles in this triangle is
then

Hence,

Find the measures of the triangle ABC:

It should be B. The dash-line triangle is half the size of the solid-lined triangle. You can find the scale factor by finding the ratio between the side lengths of the two triangles. The scale factor in this case is 2 because you are reducing thr solid-lined triangle by one half. If you are reducing by a fraction, it means that you are enlarging be the reciprical of the fraction. As reducing implies division and dividing a fraction is equivalent to multiplying by the reciprical. Thus the correct answer is B.
