1 answer:
Answer:
2291
Step-by-step explanation:
Given: Radius of a city's town hall is equal to 5-mile and about 180,000 people live in a city's town hall
To find: population density per square mile
Solution:
Population density refers to the number of people per unit of area.
Let r denotes radius of the town hall = 5 miles
Area of the town hall = square miles
Population density per square mile = Population of a city's town hall/area of the town hall = 2290.9

Answer:
Length of XM is 5.5 units.
Step-by-step explanation:
Given △XYZ where MZ is the angle bisector of ∠YZX . we have to find the length of XM.
A triangle with vertices X, Y, and Z. Side XZ is base. A line segment drawn from Z to M bisects ∠YZX into two parts ∠YZM and ∠XZM.
YZ=7 units, XZ=11 units and YM=3.5 units
By angle bisector theorem which states that an angle bisector of an angle divides the opposite side in two segments that are proportional to the another two sides of the triangle.
Hence,
⇒
⇒ MX=5.5 units.
Hence, length of XM is 5.5 units.
