Find the length of the chord of a circle of radius 100 feet subtended by an angle of 75◦ ?
miskamm [114]
1. By definition, the chord of a circle is a segment that joins the two points of an arch and if it passes through the center of the circle, is called "diameter". There is a formula that you can use to find the chord lenght. This is:

 Chord lenght=2rSin(A/2)

 2. Let's convert the angle from degrees to radians:

 75°π/180°=5π/12

 3. So, you have:

 r: It is the radius of the circle (r=100 feet).
 Sin: It is the sine function.
 A: It is the angle subtended at the center by the chord (A=5π/12).
 

 4. When you substitute these values into the formula (Chord lenght=2rSin(A/2)), you obtain the chord lenght:

 Chord lenght=2rSin(A/2)
 Chord lenght=2(200 feet)(Sin(5π/12/2))

 5. Therefore lenght of the chord is:
 Chord lenght=18.2706 feet

parallelogram ABCD is reflected over the y axis, followed by a reflection over the x axis, and then rotated 180 degrees about th
mixer [17]

Answer: Option c.

Step-by-step explanation:

The missing figure is attached.

Given a point (x,y):

1. If it is reflected over the y-axis:

(x,y) → (-x,y)

2. If it is reflected over the x-axis:

(x,y) → (x,-y)

3. If it is rotated 180 degrees about the origin:

(x,y) → (-x, -y)

In this case, you can identify that the point A is:

A(-5,1)

Then:

If it is reflected over the y-axis:

(-5,1) → (5,1)

If then it is reflected over the x-axis:

(5,1) → (5,-1)

Finally, if this is followed by a rotationf of 180 degrees about the origin, this is:

(5,-1) → (-5,1)

kaheart [24]

Answer:

It's a tie!

Step-by-step explanation:

The reason it was a tie is because

56/98 = 0.57 meaning that 57% of Restaurant A won

84/147 = 0.57 meaning that 57% of Restaurant B also won!
