An angle measures 118° less than the measure of a supplementary angle. What is the measure of each angle

Alex787 [66]

Supplementary angles add up to 180°

x = greater supplementary angle
x - 118 = lesser angle

x + (x - 118) = 180
2x - 118 = 180
2x = 298
x = 149

x - 118
149 - 118 = 31

the angles are 31° and 149°

What is the value of x<br> 2(3x+4)=5x+3x-4

stiks02 [169]

Answer:

x=6

Step-by-step explanation:

2(3x+4)=5x+3x-4

combine all like terms and distribute

6x+8=8x-4

-8 -8

6x= 8x-12

-8x -8x

-2x= -12

x= 6

The volume of a? cone-shaped hole is 49 pi ft cubed . If the hole is 3 ft? deep, what is the radius of the? hole?

lidiya [134]

$\bf \textit{volume of a cone}\\\\ V=\cfrac{\pi r^2 h}{3}~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ h=3\\ V=49\pi \end{cases}\implies 49\pi =\cfrac{\pi r^2(3)}{3}\implies 49\pi =\pi r^2 \\\\\\ \cfrac{49\pi }{\pi }=r^2\implies 49=r^2\implies \sqrt{49}=r\implies 7=r$

Find the missing factor BBB that makes the equality true. -35x^6=(-5x^2)(B)−35x 6 =(−5x 2 )(B)minus, 35, x, start superscript, 6

Sveta_85 [38]

Answer:

$B=7x^4$

Step-by-step explanation:

The given equality is

$-35x^6=(-5x^2)B$

Take the term $(-5x^2)$ to the left hand side. This means the term $-35x^6$ will be divided by $(-5x^2)$

$\dfrac{-35x^6}{(-5x^2)}=B$

Now since both the numerator and denominator have negative sign the value of fraction will be positive.

$\dfrac{35x^6}{(5x^2)}=B$

Now $5\times 7=35$ and $x^{6-2}=x^4$

$7x^4=B$

So, the missing factor $B=7x^4$

The horizontal line segment at the top of the polygon on the grid below is how many units long?

Ymorist [56]

Answer:

6 units long.

Step-by-step explanation:

Given:

A polygon drawn on a graph.

In order to determine the distance of the horizontal line at the top, we find the coordinates of the end points and then use distance formula to find the exact distance.

Let us label the polygon as ABCD as shown below. AB is the length of the horizontal line.

Coordinates of A are $(x_1,y_1)=(-3, 4)$ as seen in the graph.

Coordinates of B are $(x_2,y_2)=( 3, 4)$ as seen in the graph.

Now, distance formula for two points $(x_1,y_1)\ and\ (x_2,y_2)$ is:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d_{AB}=\sqrt{(3-(-3))^2+(4-4)^2}\\d_{AB}=\sqrt{(3+3)^2+0}\\d_{AB}=\sqrt{36}=6\ units$

Therefore, the horizontal line at the top is 6 units long.
