Determine whether the statement is always, sometimes, or never true.
The acute interior angles of a right triangle are complementary.
always
sometimes
never
Answer:
The acute interior angles of a right triangle are complementary.
Step-by-step explanation:
that if an acute angle and the obtuse angle is added, its sum is 180 degrees. ⟹ (5θ + 4°) + (θ – 2°) + (3θ + 7°) = 180°. A supplementary angle can be composed of one a cute angle and another obtuse angle. Thanks 0. y = 180 -x. range of x = [1º 89º] then range of y is [91º 179º] so this proves that always the supplementary to acute angle is always obtuse.
I hope this helped have a good rest of your day
Answer:
Always
Step-by-step explanation:
Let's name the acute angles x and y,
We are given that it's a right triangle so one angle is 90 degrees.
Sums of angles in a triangle add up to 180 degrees.
So,
x+y+90=180
x+y=90
The acute angles add up to 90 degrees so they are complementary.

What is a good newspaper article?Good research and the right organizational structure are the key constituents of writing an impactful newspaper article. Besides that, elements like interesting lead, catchy headlines, bylines, and good additional information are the basic parts of a successful newspaper article.
Since, News articles are written in a structure known as the “inverted pyramid.”
In the inverted pyramid format, the most newsworthy information goes at the beginning of the story and the least newsworthy information goes at the end.

Answer:
231cm squared
Step-by-step explanation:
9 x 22 = 198.
198 / 2 = 99
triangle area = 99
15 x 22 = 330
total area = 330
330 - 99 = 231

7
Step-by-step explanation:
Answer:
x = -4
Step-by-step explanation:
-9 (1/2x - 3) = 45
Divide both sides by -9
1/2x - 3 = -5
Add 3 to both sides
1/2x = -2
multiply both sides by 2
x = -4

I know that -3.4 is a rational number because it is an integer or decimal not equal to zero.
Step-by-step explanation:
Explanations to first:
0.147 is rational because you can write it out.0.147 bar is rational because it can be written as a fraction.Y is larger because the numbers keep repeating, so it has a larger value than 0.147.I need help on this darn dang question "The streets of Millston are laid out like a grid, with each square being the same size.

Step-by-step explanation:
plaese help me finish this part of the study guide please
Answer:
Part A: The equations are:
y = -1/2x + 2, and
y = 3x - 5
Part B: The solution is (2,1)
Step-by-step explanation:
Part A: There are two equations we need to find, each line is the graph of a function.Graphs are written in y = mx + b, m is the slope, which is the change in y divided by the change in x, and b is the y - intercept. To find the function of the first graph, the one going slightly down, the slope is: y goes down by one, and x increases by 2, so change in y/ change in x is -1/2. The y - intercept is where the graph goes through the point where x is 0, on this graph, the point is (0,2), the y - intercept is 2, so y = mx + b is y = -1/2x + 2
For the other equation, slope is when y increases by 3, x increases by 1, so 3/1, or 3. The y - intercept is -5, so y = 3x + (-5), or y = 3x - 5
Part B: The solution to this equation is the point where both of the functions meet, here, this point is (2,1), y is 2 and x is 1.

Can someone give me a small lesson on nets and surface areas??
Thank you if you can. I really don’t understand.
Hi!
Here is the definition of a net from www.icoachmath.com:
“Net is a two-dimensional pattern of a three-dimensional figure that can be folded to form the figure. In other words, net is a flattened three-dimensional figure which can be turned into the solid by folding it.”
In the photo is an example of a net of a rectangular prism.
Surface area is the measure of the total area of the surface of a 3D object. For example, if I have a cube, the surface area would be the area of the outside of the cube.
