Answer:
3^2 + x^2 = 9^2
9 + x^2 = 81
x^2 = 72
x = [tex]\sqrt{72\\}[/tex], which is about 8.5
Cosine X = 3/9
Cosine X = 1/3
angle x= 70.5
If angle x= 70.5, angle z = 19.5 degrees.

Write an equivalent expression by distributing the "-−" sign outside the parentheses: -(-4.2w-7x-5.4)
Answers
Answer: 4.2*w + 7*x + 5.4
Step-by-step explanation:
Here we need to remember how the product of different signs works, here is the rule:
(+)*(+) = (+)
(+)*(-) = (-)
(-)*(+) = (-)
(-)*(-) = (+)
Now we want to distribute the negative sign in the equation:
"-(-4.2w-7x-5.4)"
We can write this as:
-(-4.2w-7x-5.4) = (-1)*(-4.2w-7x-5.4)
Now we can distribute the "-1"
Then we get:
(-1)*(-4.2w) + (-1)*(-7x) + (-1)*(-5.4)
We have 3 cases where we need to use the "(-)*(-) = (+)" rule, then we get:
(-1)*(-4.2w) + (-1)*(-7x) + (-1)*(-5.4) = 4.2*w + 7*x + 5.4

D)82.5
Answers
Answer:
55
Step-by-step explanation:
AB // DC
∠B + ∠C = 2x + 15 + x = 180
3x = 165
x = 55
Answer: B. 55
Step-by-step explanation:
You need to know that within one parallelogram, the same-side interior angles are supplementary angles, meaning that they add up to 180°.
---------------------------------------------------------------------------------------
Given
(2x+15)+x=180
Expand parenthesis
2x+15+x=180
Combine like terms
3x+15=180
Subtract 15 on both sides
3x+15-15=180-15
3x=165
Divide 3 on both sides
3x/3=165/3
x=55

Ok you're talking about "PI"
Area of a circle:
πr^2
What that basically means is
π <- That sign is 3.14
You wanna times that with the radius (r).
The radius is half of the diamater so divde the diameter by 2 then mutiply whatever u get with 3.14
Then the final step is do 3.14 x radias then times 2.
That's it :D

Triangle A) perpendicular cross section of a cylinder
Rectangle B) shape created when a right triangle is rotated about the y-axis
Circle C) shape created when a rectangle is rotated about the y-axis
Cylinder D) parallel cross section of a sphere
Cone E) perpendicular cross section of a pyramid
Answers
Answer:
Step-by-step explanation:
Perpendicular cross section of a pyramid ------- triangle.
Imagine you cut pyramid like that. Height of pyramid would be height of your triangle. and sides of pyramid would be sides of triangle.
Perpendicular cross section of a cylinder ------- rectangle
diameter of a base of cylinder would be one side of rectangle and height of cylinder would be other side of rectangle. (pair of sides)
parallel cross section of a sphere ------ circle
when you cut sphere a side would appear with shape of circle.
shape create.... ----- cylinder.
one side of rectangle would be high of cylinder and other would be radius of it.
last one is cone. If you place right angle in coordinate beginning (0.0) and one of shorter sides to lie on y axis other would be on x axis. when rotated you get cone.

Explain how feel about trump being impeached a second time this time for the mobs action
Answers
Answer:
Trump needed to be impeached for his words and actions that led to the mob action.
He created the atmosphere of distrust in the election results by making statements that the only way he could lose the election would be if there was massive fraud. Then, when he lost the election, he used that as "proof" that there had been fraud. That is distorted logic.
Many of Trump's followers believed his claim that he had won the election, and they came to Washington DC for the rally to support him. Many of them were prepared to commit acts of violence against the members of the Congress, the senators and Vice-president Pence to prevent them from counting the votes from the Electoral College. The Trump followers believed that he could continue as president if they literally fought for him.
They invaded the Capitol and terrorized the elected officials. People died in the attack. And it could have been much worse.
None of that would have happened if not for Trump deluding them, inviting them, and encouraging them.
He must be held accountable.
Step-by-step explanation:
Opinions matter. People should form them based on facts. Facts can be verified and checked. There is a difference between assertions and facts. People can make assertions that are not true. Maybe they are mistaken. Maybe they were confused. People can admit their mistakes and correct the errors.
Some assertions are delusional: the person who makes the statement actually believes something that is not based on facts, and cannot be convinced otherwise.
Some assertions are lies, spoken to deceive others; they deliberately hide or distort the truth.

Simplify 5x - 3(x – 2) – x
Answers
Answer:
x - 2
Step-by-step explanation:
distributive property first since you stick with parentheses first (PEMDAS)
so 3x - 6 is what it would be.. then you would want to think of the equation as 5x - 3x - 2 - x. seems somewhat complicated but to others not so much.
Next you’re gonna just want to subtract, but you should probably make the problem easier so you can just subtract across right? it’d be 5x - 3x - x - 2. that way all the x variables are together and anything else is separate.
5x - 3x is 2x - x or - 1x is x or 1x.
i think just using the variable x for it being 1 is easier so now we have the problem x - 2.
anything else? nope! that’s the simplified equation.
hope that i was able to help :)
