Answer:
x = 14[tex]\sqrt{2}[/tex]
y = 14
z= 14[tex]\sqrt{3}[/tex]
Step-by-step explanation:
Notice that the top triangle is a 45-45-90 triangle and the triangle below is a 30-60-90 triangle.
Using the fact that the top triangle is a 45-45-90 triangle and also an isosceles triangle, we can see that x will be the same as its respective leg, 14[tex]\sqrt{2}[/tex]
Now, we must find a side length of the bottom triangle. We can use the Pythagorean Theorem to find the third side of the top triangle, which is also a side of the bottom triangle. We can find that the third side must be 28. We can now use this to find the other sides of the bottom triangle.
Since y is opposite to the 30 degree angle, it is half of the hypotenuse. The hypotenuse which we found earlier is 28, therefore, y is 14. z is then 14[tex]\sqrt{3}[/tex] using either Pythagorean Theorem or special right triangle properties for 30-60-90.

Answer:
20.25
Step-by-step explanation:
i think its asking for the long side
the pythagorean theorem states that in a right triangle a^2+b^2=c^2
a is 19
b is 7
c is the long side
19^2= 361
6^2= 49
361+49=410
410 =c^2
square root of 410 = ~20.25
Answer:
[tex]hypotenuse = \sqrt{ {19}^{2} + {7}^{2}} \\ = \sqrt{361 + 49} = \sqrt{410} \\ = 20.25[/tex]
20.25 is the right answer.

Answer: g=5
Step-by-step explanation:
Riko wants to find the distance between the points (−2, −3) and (2, −5). His work is shown. StartAbsoluteValue negative 3 EndAbsoluteValue + StartAbsoluteValue negative 5 EndAbsoluteValue = 3 + 5 = 8. The distance is 8 units. Riko correct? Explain why or why not.
Answers
Answer:
Riko is wrong because she uses the wrong formula.
Step-by-step explanation:
Given the coordinate points (-2, -3) and (2, -5)
We are to find the distance between the two points
Using the formula:
D = √(x2-x1)²+(y2-y1)²
From the coordinates x1 = -2, y1 = -3, x2 = 2 and y2 = -5
Substitute
D = √(2-(-2))²+(-5-(-3))²
D= √(4)²+(-2)²
D = √16 + 4
D = √20
D = √4*√5
D = 2√5
This shows that Riko is wrong because she uses the wrong formula.
Answer:
No, Riko is not correct. The points do not have the same x-coordinates. If you connect the points, they do not form a horizontal or vertical line, so you cannot count spaces or use absolute value to find the distance.
Step-by-step explanation:
Can someone please explain slope in a way that might make sense.
Answers
The slope of an equation or graph is the rate of change.
In order to find slope, we use the formula m=rise/run or m=y2-y1/x2-x1
“m” is equal to the slope
“rise” or “y2-y1” is the difference (subtraction) of the two y coordinates
“run” or “x2-x1” is the difference (subtraction) of the two x coordinates
Remember, the points we are using for this example are (4, 1) and (-2, 7)
m = y2-y1/x2-x1
m = 7-1/-2-4
1 and 7 are your y coordinates so you plug them in an find the difference (subtraction)
4 and -2 are your x coordinates so you plug them in an find the difference (subtraction)
It doesn’t matter whether you do “m=7-1/-2-4” or “m=1-7/4-(-2)” both will have the same answer
The only thing you can’t do is something like “m=7-1/4-(-2)” or “m=1-7/-2-4”
The bottom can’t be solved in the opposite way of how it was solved on top and vice versa of that makes sense
Also, keep in mind that if you see two negatives as in the “m=1-7/4-(-2)” example, you turn it into an addition symbol
Like this:
“m=1-7/4+2)”
Because two negatives are equal to a positive
m = y2-y1/x2-x1
m = 7-1/-2-4
m = 6/-6
m = 6/-6
m = -1
Remember that a negative divided by a positive is always a negative so it doesn’t matter where you place the negative sign
For example, if your slope was 2/-5, that would be the same as -2/5
And when you divide two negatives, it always equals to a positive
For example -2/-5 would simplify to 2/5
I hope that helped and made sense :)

What expression can you substitute for y in

-4y + x = -27
Enter the correct answer.
Answers
Answer:
1/4x+27/4
Step-by-step explanation:
Here's the equation: -4y+x=-27
We'll need to isolate y on one side
subtract x from both sides
-4y=-x-27
divide everything by -4
y=1/4x+27/4
So you can substitute 1/4x+27/4 for y.
