What is the length of side EF in the triangle? Please give a step by step explanation, I'm having lots of trouble finding the solution. Thank you!
Answers
Answer:
EF = 8.8 cm
Step-by-step explanation:
In the given right angled ΔDEF, DE is the hypotenuse while EF and DF are adjacent sides. So that applying the Pythagoras theorem, we have;
[tex]/hyp/^{2}[/tex] = [tex]/adj1/^{2}[/tex] + [tex]/adj2/^{2}[/tex]
[tex]/DE/^{2}[/tex] = [tex]/EF/^{2}[/tex] + [tex]/DF/^{2}[/tex]
[tex]/16.2/^{2}[/tex] = [tex]/EF/^{2}[/tex] + [tex]/13.6/^{2}[/tex]
262.44 = [tex]/EF/^{2}[/tex] + 184.96
[tex]/EF/^{2}[/tex] = 262.44 - 184.96
= 77.48
EF = [tex]\sqrt{77.48}[/tex]
= 8.8023
EF = 8.8 cm
The length of side EF is 8.8 cm.

O D. = 3.c – 2
Answers
Answer: y= D.3x-2
Step-by-step explanation:
Explanation:
To find the slope of two points, we need to use the formula m=rise/run or m=y2-y1/x2-x1
-2-7 -9
m = ——— = — = 3
-2-1 -3
Now we have to find “b” as in the equation “y=mx+b”
We already have our “m” which is the slope and that is equal to 3
In order to fine “b,” we have to set it up in point slope form which is the formula
“y-y1 = m(x-x1)”
You can choose to set this up with either one of the coordinates given
In this problem, the coordinates given are
(-2, -2) and (1, 7)
I’m going to use the coordinates (1, 7)
y-y1 = m(x-x1)
y-7 = 3(x-1)
The “7” is the y point
The “3” is the slope
The “1” is the x point
Now we simplify the equation:
y-7 = 3(x-1)
y-7 = 3x-3
+7 +7
—————
y = 3x + 4
Hope this helps and makes sense :)

Step-by-step explanation:
The opposite sides of a parallelogram must be parallel to each other, and this is shown by the equivalent opposite interior angles on each side of the bisector.
Since the opposite sides of a parallelogram are parallel, they must be of equal length (this is one of the fundamental properties of a parallelogram).
Therefore, we can set (18x - 5) and (16x + 5) equal to each other in an equation and solve for x.
18x - 5 = 16x + 5Subtract 16x from both sides.
2x - 5 = 5Add 5 to both sides.
2x = 10Divide both sides by 2.
x = 5The value of 5 for x must make ABCD a parallelogram.

Step-by-step explanation:
Given
[tex]\sqrt{21}[/tex][tex]4\frac{2}{3}[/tex]as
[tex]\:\sqrt{21}=4.58[/tex]
and
[tex]4\frac{2}{3}[/tex]
Convert mixed numbers to improper fraction:
[tex]a\frac{b}{c}=\frac{a\cdot \:c+b}{c}[/tex]
so
[tex]4\frac{2}{3}=\frac{4\cdot 3+2}{3}=\frac{14}{3}=4.67[/tex]
Thus,
[tex]\:\sqrt{21}=4.58[/tex]
[tex]4\frac{2}{3}=4.67[/tex]
as
4.67 > 4.58
so
[tex]4\frac{2}{3}[/tex] > [tex]\sqrt{21}[/tex]
Hence, we conclude that
[tex]4\frac{2}{3}[/tex] > [tex]\sqrt{21}[/tex]
