Please help me because I don’t know

The magnitude of angle Z include the following:

cosZ = 0.471

sinZ = 0.88

tanZ = 1.875

In order to determine the magnitude of angle Z, we would apply the basic trigonometric ratio because the given side lengths represent the adjacent side, opposite side, and hypotenuse of a right-angled triangle.

cos(θ) = Adj/Hyp

Where:

For cosZ, we would apply the cosine trigonometric ratio as follows;

cosZ = 13.6/28.9

cosZ = 0.4706

Z = cos⁻¹(0.4706)

Z = 61.93°.

For sinZ, we would apply the sine trigonometric ratio as follows;

sinZ = 25.5/28.9

sinZ = 0.8824

Z = sin⁻¹(0.8824)

Z = 118.07.

For tanZ, we would apply the sine trigonometric ratio as follows;

tanZ = 25.5/13.6

tanZ = 1.875

Z = tan⁻¹(1.875)

Z = 61.93.

The dot isn’t shaded so > or <

From -55, it’s showing small than

From -49, it’s showing greater than

x < -55 or x > -49

Answer:  x < -55 or x > -49

Step-by-step explanation:

x < -55 or x > -49

They both start with an opened circle, and also these two opened circle dots do not connect to each other. On the left side, the number is going from -55 to the smaller side, -57 or less, so we can say that x is smaller than -55. On the right side, the number goes from -49 to the bigger number, we can say that x is greater than -49.

Answer:

24.7

Step-by-step explanation:

If your weekly salary is $1780 and taxes takes out $440, then 24.7% you pay in taxes.

percentage, a relative value indicating hundredth parts of any quantity.

Given that the weekly salary is One thousand seven hundred and eighty $1780.

Taxes takes out is four hundred and forty $440.

We need to find the percent of tax we have paid.

This can be found by as below.

1780x=440

Divide both sides by 1780

x=440/1780

x=0.247

Now multiply with 100 as it is a hundredth part

0.247×100=24.7%

Hence, 24.7% is the percentage of tax we have paid.

Answer:

[tex]$(x-h)^2+(y-k)^2= (r+ 40 )^2$[/tex]  

Step-by-step explanation:

It is given that a meteorologist is using a Doppler radar to find out the distance of the storm as it passes using a polar grid.

The origin of the radar screen is its center.

And the distance between each ring is 10 miles from the center.

So let :

r = radius

h and k = be the coordinates of the center.

So the equation of a circle is :

[tex]$(x-h)^2+(y-k)^2= r^2 $[/tex]

Now the equation of the fourth circle when the radius changes by 10 miles is :

[tex]$(x-h)^2+(y-k)^2= (r+ 40 )^2$[/tex]

Answer:

  when it is a rhombus

Step-by-step explanation:

A kite is a figure in which the diagonals are perpendicular, and one of them is bisected by the other. It will be a parallelogram if both diagonals bisect each other. Such a figure (with mutually perpendicular bisectors as diagonals) is a rhombus.

A parallelogram that is a rhombus will also be a kite.
