Answer:
1 ) m∠ 1 = 72°, m∠2 = 108°,
2 ) m∠ 1 = 22.5°, m∠2 = 67.5°
Step-by-step explanation:
Question 2 ) Assuming these are supplementary angles, we know that their measures form a linear pair that add to 180°;
let us assign these angles as 1, and 2 ⇒ m∠ 1 + m∠ 2 = 180,
with the given ratios 2 to 3, we can say x ⇒ one part of measure, so that ⇒ 2x + 3x = 180,
2x + 3x = 180 ⇒ combine like terms,
5x = 180 ⇒ divide either side by 5,
x = 36°
If this is so, m∠ 1 = 2x = 2 * ( 36 ) = 72°, and m∠ 2 = 3x = 3 * ( 36 ) = 108°;
Solution; m∠ 1 = 72°, m∠2 = 108°
Question 3 ) If it is known that two angles are complementary to one another, we can say their measures add to 90°;
let us one more, assign these angles as 1 and 2 ⇒ m∠ 1 + m∠ 2 = 180,
knowing that the measure of one angle is 3 times that of the other angle we can derive the ratio 1 : 3 in the manner smaller ∠ measure : bigger ∠ measure so that ⇒ x + 3x = 90,
x + 3x = 90 ⇒ combine like terms,
4x = 90 ⇒ divide either side by 4,
x = 22.5
If this is so, m∠ 1 = x = 1 * ( 22.5 ) = 22.5°, and m∠ 2 = 3x = 3 * ( 22.5 ) = 67.5°;
Solution; m∠ 1 = 22.5°, m∠2 = 67.5°

5 12 13 triple
Answer:
r =5
Step-by-step explanation:
We can use the Pythagorean theorem
a^2 + b^2 = c^2
The legs are r and 12
The hypotenuse is (8+r)
r^2 + 12^2 = (8+r)^2
r^2 + 144 = 64 + r^2 +16r
Subtract r^2 from each side
144 = 64 +16r
Subtract 64 from each side
144-64 = 16r
80 = 16r
Divide each side by 16
80/16 = 16r/16
5 =r

The range of which function includes -4?
O y= √x-5
O y= √x+5
O y= √x+5
O y=√x-5
Answer: A is the correct answer .
Start with the last two choices .
You have x+ 5 and × - 5 in the square root .
A square root can never be negative .
That means that the lowest value of y can have in the last two choices is 0 .
Now range doesn't include -4.
Now look at choice B .
sqrt (x) is at least 0.
Then you add 5 .
The range doesn't include -4.
Now look at choice A .
sqrt (x) is at lest 0 .
Now ,you subract 5 .
The lowest value y can have is -5 . That includes -4.
Choice A is the answer .
y will be at least 5

One supplementary angle is 15 degrees less than twice the other. Find the measure of the two supplementary angles.
Hey there!
To find our answer, we need to set up a system of equations. Remember, supplementary angles equal 180 degrees when combined. We will call one of our angles A and the other one B. Let's set it up below! :)
A=2B-15 (one angle is 15 degrees less than twice the other)
A+B=180
We need to find one of our variables. To do this, we only put one variable in the equation. But how, there are two variables in both equations! Well, as you can see, we see the A is equal to 2B-15, so we can take 2B-15 and put it into the second equation in place of A because it is equal to A, and then we will only have Bs and we can solve for it. This method is known as solving systems of equations with substitution.
Let's solve with substitution!
2B-15+B=180
3B-15=180 We combine our Bs.
3B=195 We add 15 to both sides.
B= 65 We divide both sides by three.
Now, we need to find what A is, but this will be really easy to do! If you remember, our angles are supplementary, so when you combine them, we will get 180, as you can see in our second equation in our first system of equations. So, we simply subtract 65 from 180.
180-65=115
Our two angles are 65° and 115°.
We can also check this with the original problem.
If you double 65, we have 130. Then, if we subtract 15, we have 115. Systems of equations are a pretty awesome way to figure this out!
I hope this helps! Have a great day!

Select the linear equation represented in the graph
a) y= 2x+3
b) y= 1/2x+3
c) y= 1/2x-3
d) y=-2x-3
Answer:
B
Step-by-step explanation:
Since the line in the picture rises 1 unit for every 2 units it moves to the right, it has a slope of 1/2. Also, since it intersects the y axis at (0,3), the y intercept is 3. Therefore, the equation of the line is y=1/2x+3, or answer choice B. Hope this helps!

Variance and standard deviation
Answer: 8.3
Step-by-step explanation:
To find the variance, you want to find the mean of the data.
[tex]\frac{3+3+8+1+9+6}{6} =5[/tex]
Now that we have the mean, we find the difference between each data point and the mean.
3-5=-2
3-5=-2
8-5=3
1-5=-4
9-5=4
6-5=1
With the difference, you square each and find the average.
(-2)²=4
(-2)²=4
3²=9
(-4)²=16
4²=16
1²=1
[tex]\frac{4+4+9+16+16+1}{6} =\frac{25}{3}[/tex]
The variance is 8.3.

Plot the 3 possible points for the 4th vertex.
Answer:
(-1, -1), (-3,5), (5, -3)
Step-by-step explanation:
(-1, -1) is the 4th vertex.
Which is the required vertex ?Let, 4th vertex is (x, y)
Given vertices of parallelogram are (-2. 2), (1, 1), (2, -2)
Here, (-2. 2) & (2, -2) are opposite vertices.
So, Midpoint of diagonals = [tex][(\frac{-2+2}{2}) ,(\frac{2-2}{2})][/tex] = (0, 0)
This is also midpoint of diagonal with vertices (1, 1) & (x, y)
So, (1+x)/2=0 ⇒ x = -1
& (1+y)/2=0 ⇒ y = -1
∴ 4th vertex is (-1, -1)
