Answer: C) 3

Explanation:

Point A is located at (0,2). It moves to A ' (0,6). Focus on the y coordinates. We go from y = 2 to y = 6. This is a jump of multiplying by 3. We have multiplied every coordinate of A by 3 to get corresponding coordinates for A'.

Point B will be treated the same way. It starts off at B = (2,3) and moves to B ' = (6,9) after multiplying both coordinates by the same scale factor 3.

The length of AB will also be tripled

length of A'B' = 3*(length of AB)

Answer:

The value of x is $31^{\circ}$ .

Step-by-step explanation:

Please look at the figure attached to get more clear solution.

We have given:

FG||CB

And the line that cut the parallel line is transversal so, here BA is transversal

And alternate interior angles on transverse line are equal

So, ∠1=∠4

And ∠4= $28^{\circ}$

Hence, ∠1=∠4= $28^{\circ}$

And On FG the sum of angles will be $180^{\circ}$

∠3+∠2+∠1= $180^{\circ}$

$90^{\circ}$ +∠2+ $28^{\circ}$ = $180^{\circ}$

Hence, ∠2= $62^{\circ}$

Now, we know that the sum of interior angles is equal to the exterior angle:

Therefore, ∠2+∠5=∠6+∠7

$62^{\circ}+3x=x+4x$

On simplification we get:

$2x=62^{\circ}$

$x=31^{\circ}$

Hence, the value of x is $31^{\circ}$ .
