Two ropes are attached to a large ballon in a parade. The people holding the ropes are 40 feet apart,and the angle between the t

qaws [65]

Ropes are 9.63 meters ans 8.178 meters.

<u>Step-by-step explanation:</u>

Step 1 :

List all the given things

Distance between people holding ropes = 40 =(40*0.3048) meters = 12.192 meters

Angle between two ropes = 86 degrees

Angle of elevation of one rope = 42 degrees

Step 2 :

Two angles of triangle are already given so third angle can be calculated as -

Third angle = 180 - ( 86 + 42 ) = 52 degrees

Step 3 :

As we know all three angles we will apply sine rule now, which is

$\frac{a}{sine A} = \frac{b}{sine B} = \frac{c}{sine C}$

Step 4 :

By putting values, we have

$\frac{a}{sine 52} = \frac{b}{sine 42} = \frac{12.192}{sine 86}$

Step 5 : Calculating a and b

$a = 12.192 * \frac{sine 52}{sine 86}$ , $b = 12.192 * \frac{sine 42}{sine 86}$

Step 6 :

By putting values of all sine and calculating we get,

a = 9.63 meters and b = 8.178 meters

The circle given by

mixer [17]

Typically, the equation of a circle is given like this: (x-h)^2 + (y-k)^2 = r^2, where r is the radius of the circle and the point (h,k) is the center. To find the value k, you need to put the first equation you have into this form. Standard form requires that you only have the1 y variable, as seen in the parentheses, so you first need to complete the square.

x^2 + y^2 - 2y = 11
x^2 + y^2 - 2y +1 = 11 + 1
x^2 + (y - 1)^2 = 12

And that puts the equation in standard form. k = 1.

List parallelograms, polygons, quadrilaterals, and rectangles in order from the least specific group to the most specific one.

a_sh-v [17]

Answer:

(B)

Step-by-step explanation:

Option (B) is in correct order when talking about the specific ones.

Polygon is the least specific as it can be of many sides.

example: A polygon with 3 sides is a triangle. and the polygon with 4 sides is a quadrilateral.

Hence, quadrilateral is on the second number in least specific group.

Quadrilaterals with 2 sides parallel and equal are known as parallelogram.

Therefore, they are on the 3rd number in specific group.

Parallelograms with opposite sides parallel and equal and all the vertex angles at right angles are known as rectangles.

Therefore, rectangles are the most specific one in the group. The list is given by (option (B):

1) polygons

2) quadrilaterals

3) parallelograms

4) rectangles.
