Answer:

Angle 6 = 46°

Angle 7 = 134°

Angle 8 = 77°

Step-by-step explanation:

Angle 6 = 180 - 134 (Due to the angles on a straight line add up to 180 property)

Angle 6 = 46°

Angle 7 = 180 - 46

Angle 7 = 134°

360 = 56+148+(2 x Angle 8)

2 x Angle 8 = 360-204

2 x Angle 8 = 156

Angle 8 = 78°

About 150,000 people live in a circular region with a population density of about
morpeh [17]

Area of a circle = pi x r^2

Area of circle = 150,000/ 1578 = 95.06 square miles

95.06 = 3.14 x r ^2

Divide both sides by 3.14

R^2 = 30.27

Find the square root:

R = sqrt(30.27)

R = 5.5

The radius is c) 5.5 miles
