Can soomeone help me on this one too
Answers
Answer:
70°
Step-by-step explanation:
An euclidean triangle (a triangle on a straight plane) has sum of three angles equal to 180°.
When we talk about a triangle, we usually talk about an euclidean one.
There are also a non-euclidean triangles which are a triangle on circular plane which has sum of angles above 180° and one that is a hyperbolic triangle version which has sum below 180°.
Back to the question, since we know that the triangle is an euclidean one and thus has the sum equal 180°.
x+20+40+2x-30 = 180
Combine like terms:
3x+30=180
Subtract both sides:
3x+30-30=180-30
3x=150
Divide both sides by 3.
3x/3 = 150/3
x = 50
Since we want to find angle B which has measure of 2x-30, substitute x = 50 in 2x-30.
2(50)-30 = 100-30 = 70
Therefore angle B is 70°

is y=x2-1 a linear function
Answers
Answer:
No, it is a quadratic function
Step-by-step explanation:
If you mean y=x²-1, then it is a quadratic, since we have x to the 2nd power.
If we had an equation in the form of y=mx+b, where m is the slope and b is the y intercept, it is linear.
An example of a linear function would be, y=6x-5
Ann made $143 for 11 hours of work.
At the same rate, how many hours of work would she have to work to make $243
Answers
Answer:
22 hours
Step-by-step explanation:
So, 143 equals eleven hours. 143 plus 143 would equal 243. So, you have two 143s which means you should multiply the 11 hours by two. 11x2 equals 22.

A regular octagon is shown below. Suppose that the octagon is rotated clockwise about its center so that the vertex at Y is moved to 7. How many degrees
does the octagon rotate?
Answers
Answer:
I believe it says the vertex at Y is moved to T:
the angle of each side changes by 360 / 8 = 45 at each vertex
If 3 vertices separate Y and T the the total rotation would be
3 * 45 = 135 deg
The octagon rotated 135 degree.
What is an Octagon?An octagon is a polygon with eight sides.
The total angle at the center is 360 degree and for a regular octagon, the angle made by each side is equal to 360/8 = 45 degree.
The octagon STUVWXYZ is rotated clockwise such that, the vertex Y moves to T.
Movement of Y to T is moving 3 steps clockwise
= 45* 3
= 135 degree

To solve the equation: First, subtract 9 from both sides of the equation. Second, divide both sides of the equation by -10
Step-by-step explanation:
We are subtracting from both sides because we need to do the inverse, and the inverse of adding 9 is subtracting it.
Same with the -10. We need to do the inverse, and the inverse of multiplying by -10 is dividing by it.
Answer:
First: Subtract 9 from both sides of the equation. Second: Divide both sides of the equation by -10
Step-by-step explanation:
because 9 is positive, to get rid of it you need to subtract it.
after than, you would get -10x = -30
you would then divide it by -10 because you need to get x by itself
x = -3
