A=s^2~~
\begin{cases}
s=side's~length\\
--------\\
A=\frac{4}{9}
\end{cases}\implies \cfrac{4}{9}=s^2

My math final please help
spin [16.1K]

Answer:

m∠3 = 56

Step-by-step explanation:

Let's solve for x, first:

x + 9 = 3x - 85

9 = 2x - 85

94 = 2x

94/2 = x

47 = x

Now that we have x-value, we can substitute it in any one of the given equation to find angle 3 since, angle 1, 7 and 3 all are congruent:

=> m∠7 = x + 9

=> m∠7 = 47 + 9

=> m∠7 = 56

Since m∠7 ≅ m∠3

and m∠7 = 56, then

<u>m∠3 = 56</u>

Hope this helps!

For this case, the first thing you should do is use the distance between points formula.
 We have then:
 d = root ((x2-x1) ^ 2 + (y2-y1) ^ 2)
 Substituting we have:
 d = root ((9 - (- 9)) ^ 2 + (-2-7) ^ 2)
 d = 20.1246118
 Rounding off we have:
 d = 20 units
 Answer:
 
The distance, to the nearest unit, between your house and the subway stop is:

AACB ~AEFD<br> x = [?]<br> Enter your answer in decimal form.
tia_tia [17]

Answer:

<h2>11.4</h2>

Solution,

∆ ACB = ∆ EFD

finding the value of X,

\frac{x}{3.8}  =  \frac{15}{5}

Apply cross product property

x \times 5 = 15 \times 3.8

Calculate the product

5x = 57

Divide both sides by 5

\frac{5x}{5}  =  \frac{57}{5}

Calculate

x = 11.4

Hope this helps...

Good luck on your assignment...
