Answer:
The correct option is A.
Step-by-step explanation:
It is given that DEFG is a parallelogram.
Draw the diagonals DF and EG. Place point H where DF and EG intersect.
In triangle HGD and HEF
,
∠HGD ≅ ∠HEF (Alternate Interior angle)
∠HDG ≅ ∠HFE (Alternate Interior angle)
By the definition of a parallelogram, the opposite sides of a parallelogram are congruent.
DG ≅ EF (Opposite sides of parallelogram)
According to ASA postulate :
two triangles are congruent if any two angles and their included side are equal in both triangles.
So, by using ASA criterion for congruence we get,
ΔDGH ≅ ΔFEH
Since corresponding sides of congruent triangles are congruent, therefore
GH ≅ EH (CPCTC)
DH ≅ FH (CPCTC)

In this triangle, the product of sin B and tan C is
and the product of sin Cand tan B is
Answer:
[tex]\frac{c}{a}[/tex] and [tex]\frac{b}{a}[/tex]
Step-by-step explanation:
sinB = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AC}{BC}[/tex] = [tex]\frac{b}{a}[/tex]
tanC = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AB}{AC}[/tex] = [tex]\frac{c}{b}[/tex]
Thus
sinB tanC = [tex]\frac{b}{a}[/tex] × [tex]\frac{c}{b}[/tex] ( cancel b on numerator/ denominator )
= [tex]\frac{c}{a}[/tex]
---------------------------------------------------------------------------
sinC = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{c}{a}[/tex]
tanB = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{b}{c}[/tex]
Thus
sinC tanB = [tex]\frac{c}{a}[/tex] × [tex]\frac{b}{c}[/tex] ( cancel c on numerator/ denominator )
= [tex]\frac{b}{a}[/tex]
what does this symbol mean in math: •
Answer: Multiplication
Step-by-step explanation:
Hope this helps :)
Answer:
Because it's taken out of context, I am not completely certain, but I'm pretty sure it's just another way to write the multiplication symbol. A lot of people like it because it's faster to write, and you won't confuse it with the variable x.
Hope this is helpful to you!
Subtract (4x2 - x + 6) from (3x2 + 5x - 8).
A. O 7x2 + 6x - 14
B. 7x2 + 4x - 2
C.x2 - 6x + 14
D. -x2 + 6x - 14
Answer:
[tex]\left(3x^2+5x-8\right)-\left(4x^2-x+6\right)=-x^2+6x-14[/tex]
Hence, option D is correct.
Step-by-step explanation:
We have to subtract (4x² - x + 6) from (3x² + 5x - 8).
so
[tex]\left(3x^2+5x-8\right)-\left(4x^2-x+6\right)[/tex]
Remove parentheses: [tex]\left(a\right)=a[/tex]
[tex]=3x^2+5x-8-\left(4x^2-x+6\right)[/tex]
[tex]=3x^2+5x-8-4x^2+x-6[/tex]
Group like terms
[tex]=3x^2-4x^2+5x+x-8-6[/tex]
Add similar elements: [tex]\:3x^2-4x^2=-x^2[/tex]
[tex]=-x^2+5x+x-8-6[/tex]
Add similar elements: [tex]5x+x=6x[/tex]
[tex]=-x^2+6x-8-6[/tex]
Subtract the numbers: [tex]-8-6=-14[/tex]
[tex]=-x^2+6x-14[/tex]
Therefore,
[tex]\left(3x^2+5x-8\right)-\left(4x^2-x+6\right)=-x^2+6x-14[/tex]
Hence, option D is correct.
Scale Factor = 1 is it reduction or enlarge
Answer:
The image remains the same.
Step-by-step explanation:
If the scale factor is one, then the image is not reduced or increased, it remains the same. This is because, if one multiplies the original image by the scale factor, then one will get the scaled answer. If one multiplies anything by 1, then they will get the number they multiplied by 1 (this is called the multiplicative identity property), hence the image remains the same.
Count to find the slope.
Answer:
The slope is 6/7 or -7/6.
Step-by-step explanation:
You could go from the lower dot and count to the line of the upper dot and then go to the right until you hit the dot or you would start at the upper dot and count down to the line of the lower dot and go to the left until you hit the dot.

What is system of equations?A system of equations can be defined as an algebraic equation of the first order with two (2) variables and each of its term having an exponent of one (1).
Mathematically, an equation can be represented as follows:
[tex]x+y=10[/tex]
Where:
x and y are the variable terms.Generally, the variable terms on both sides are different for an equation that has one (1) solution.
