Please solve for X. Then, circle whether each angle pair is complementary or supplementary

1 answer:

Answer:

x=11 complementary

Step-by-step explanation:

We see from the square marking that both angles add up to be 90 degrees. Knowing this, we can do 90-43 so that we know the total measure of the top angle. Doing this, we know that the top angle equals 47. We can write this out as 5x-8=47, because they are the same thing. We add 8 to both sides, and get 5x=55. Now we divide both sides by 5 and get x=11. Now we have x, so let's decide if the angle pair is complementary or supplementary. Well, supplementary means the angles add up to be 180 degrees, and complementary means they add up to 90 degrees. We already said that the angle pair added up to 90 degrees, so the angle pair is complementary.

What is the distance between (-6,4) and (-8,6)? Choose 1 answer:

lukranit [14]

Answer:

D

Step-by-step explanation:

We want to find the distance between (-6, 4) and (-8, 6).

We can use the distance formula given by:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2$

Let (-6, 4) be (x₁, y₁) and let (-8, 6) be (x₂, y₂).

Substitute:

$d=\sqrt{(-8-(-6))^2+(6-4)^2$

Evaluate:

$d=\sqrt{(-2)^2+(2)^2$

Evaluate:

$d=\sqrt{4+4}=\sqrt{8}$

Hence, our answer is D.

Janet wants to plant a square flower garden in her yard. She has enough topsoil to cover an area of 30 square feet. How long can

gregori [183]

It can be at least 5.4 feet long since the area of a square is A=s^2. 5.4 times 5.4 is 30

Solve for m.<br> 22m^2 + 7m - 2 = 0

pshichka [43]

Answer:

x= -1/2 and x=2/11

Step-by-step explanation:

Write the 7x as a difference. It'll make it easier to factor out. An example of this would be 11x-4x

Therefore, the equation would look like this: 22x^2 + 11x-4x -2 =0

Look at it as if there are two equations: 22x^2+11x and -4x-2

Factor out the greatest common factor, which is 11 from the first equation. The equation will then look like this: 11x(2x+1)

Take the GCF for the second equation as well (which is -2). The equation should then also look like this: (2x+1)

Use the numbers on the outside of each of the parenthesis to form its own equation (to factor it out). This will be 11x-2

Now we have factored! Since the parenthesis equations are the same, we know that that is also part of the equation, so:

(11x-2)(2x+1)

Solve each equation for x by equaling them both to zero
