x=75°

We know that ∠EFG=∠ABF because they are corresponding angles.

We also know that ∠x+∠ABF=180, because angles along a straight line always equal 180:

x+105=180

x=75°

Answer:

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

equation
PEMDAS

<h3>let's solve:</h3>

according to the question

$\begin{cases}x + 29 = 7x + 5 \\ 8y - 35 =3y \end{cases}$

$\begin{cases}x -7x= 5-29 \\ 8y - 3y=35 \end{cases}$

$\begin{cases}-6x= -24\\ 5y=35 \end{cases}$

$\begin{cases}\frac{-6x}{-6}=\frac{-24}{-6} \\ \frac{5y}{5}=\frac{35}{5} \end{cases}$

$\therefore \begin{cases} x=4\\ y=7 \end{cases}$

Ratio is 4:7, smaller volume is 1, 331, find larger volume

viva [34]

If the smaller volume ratio is 4 to 1331, divide 1331 by 4 to get the multiplying factor.
1331/4 = 332.75
Now we multiply 332.75 by 7 to get our larger volume.
332.75 x 7 = 2329.25
2,329 is our larger volume.
I hope this helps!
