Answer:
The answer is Tm= 2.pi.r / Vm and Tm is greater than Te.
Explanation:
V = Sqrt (GM/r)
Vm = sqrt (Gme/r)
The time taken by satellite,
Te = 2. pi. r / Ve
Tm = 2 . pi. r / Vm.
Hence, Tm is greater.

Demography is the study of human population.
<h2>
Explanation:</h2>
Demography studies most if not all aspects about human population. It checks births, death, sex, migration, etc. and in turn, when we describe the population, it is normally from pertaining to demographic. Demography is also involved in other disciplines such as sociology, economics, statistics, etc.
Through demographics, the necessary departments get to understand people and their needs better. Countries economic decisions is one example that depends on demographic studies. It also affects other areas such as the planning, labor markets analysis, and etc.
∠YXZ=58°
<h3>Further explanation</h3>
Triangles are flat fields bounded by 3 intersecting sides and 3 angles
This side can be the same length or different.
If at an angle there is an angle of 90 degrees, this triangle is said to be a right angle
∠WXV+∠WXY=∠YXV
∠WXV+∠WXY=139°
∠WXV=11+(3.∠WXY)
11+(3.∠WXY)+∠WXY=139°
11+4∠WXY=139°
4∠WXY=128°
∠WXY=32°
∠WXY+∠YXZ=90°
32°+∠YXZ=90°
∠YXZ = 90°-32°=58°
