Unit 7: Circles Lesson 1: Tangent Lines
1. AB and B are tangents to P. What is the value of x?
B
2. A satellite is 13,200 miles from the horizon of Earth, Earth's radius is about 4,000 miles. Find the approximate distance the satellite is from the Earth's surface. The diagram is not to scale.
C
3. YZ is tangent to X, and X is the center of the circle. What is the length of the radius of the circle?
B
4. The radius of G is 4 cm. Which is a tangent of G?
D
5. Circle A is inscribed in a quadrilateral. What is the perimeter of the quadrilateral?
B

is there answer choices?

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
