Find the value of x that makes ABCD a parallelogram.

olganol [36]

The angle 5x will be 50⁰. Then the correct option is D.

<h3>What is a parallelogram?</h3>

It is a polygon with four sides. The total interior angle is 360 degrees. A parallelogram's opposite sides are parallel and equal.

The diagram is given below.

We know the sum of internal angles is 360 degrees.

Then we have

5x + 130 + 5x + 130 = 360

10x = 100

x = 10

Then the angle 5x will be

5x = 5(10)

5x = 50⁰

Then the correct option is D.

More about the parallelogram link is given below.

The measures of two complementary angles are in the ratio 8:1. how many degrees are in the larger angle?

djverab [1.8K]

Since the measures of the two angles are in the ratio 8:1, this means the bigger angle's is 8x and the smaller angle is x. Since they are complementary, they add to 90°, so you create the equation 8x+x=90°. This can be simplified to 9x=90°. Then, you divide 90 by 9 to get 10. This means x=10. Next, you replace x with 10 to find the measure of the bigger angle. 8x10=80, so the larger angle is 80°.

A function has y-intercept of -2 and a slope of -1. which equation below describes the function?

ozzi

The correct equation should look something like this:
y= -1x - 2

Consider the equation for a line:
y = mx + b,
Where ‘m’ is the slope
Where ‘b’ is the y-intercept.

From there you can plug in your known values for ‘m’ and ‘b’, and get the equation above. If you are still not convinced, I suggest you graph the function and observe its slope and y-intercept.

Hope this helps!

Write the following number as ratios of integers

Grace [21]

We're going to "cut" the repeating part here in a few steps. First, we're going to put the number in a variable:

$x=-2.0\overline{42}$

Next, to get rid of the negative, we can multiply either side by -1 to get

$-x=2.0\overline{42}$

Now, we won't actually use this -x directly; instead, we want to create two new values, one by multiplying either side by 10:

$-10x=20.\overline{42}$

and the other by multiplying either side by 1000:

$-1000x=2042.\overline{42}$

Next, we can get rid of the repeated part of the number by subtracting -10x from -1000x:

$-1000x-(-10x)=2042.\overline{42}-20.\overline{42}\\ -1000x+10x=2022\\ -990x=2022$

And finally, we can divide either side of the equation by -990 to find that

$x= \frac{2022}{-990}=-\frac{2022}{990}\div \frac{6}{6}=-\frac{337}{165}$
