A rhombus is a parallelogram, namely, is a polygon with four sides and two pairs of parallel sides.

the one distinction of a rhombus with other parallelograms is that, a rhombus has all equal sides, all its four sides are the same length, so, if you already know the vertices are for a parallelogram, then is a given two pairs of sides are parallel.

so...  you simply need to check their length, making sure they're all equal, using the distance formula.

There are 9 more pencils then pens in a container. There are 25 writing utensils in the container in all. How many pens are ther
VashaNatasha [74]
In order to determine the number of pens present in the container, we need to set up equations from the given in the problem statement. We do as follows:

let x the number of pencils
    y the number of pens

From the statement, 9 more pencils then pens in a container,

x = y + 9

From the statement, there are 25 writing utensils in the container in all,

x + y = 25

We use substitution method to calculate for x and y,

y + 9 + y = 25
2y = 16
y = 8
x = 17

Therefore, there are 8 pens in the container and 17 pencils.

Solve for x. round to the nearest hundredth if necessary.
iris [78.8K]

Answer: x=11.47

Step-by-step explanation:

Given the angle of 55 degrees, you know that the adjacent side is "x" and the length of the hypotenuse is 20.

Therefore, you need to remember the following identity:

cos\alpha=\frac{adjacent}{hypotenuse}

Then, knowing that:

\alpha=55\°\\adjacent=x\\hypotenuse=20

 You need to substitute these values intocos\alpha=\frac{adjacent}{hypotenuse}:

 cos(55\°)=\frac{x}{20}

Now, you can solve for "x":

20*cos(55\°)=x\\x=11.471

Rounded to the nearest hundreth:

x=11.47
