Step-by-step explanation:

Hey there!

Now, let's look into figure.

angle ACB = 65° { Base angle of triangle ABC}

angle ACB + angle BAC + angle ABC = 180°

65° + 65° + angle ABC = 180°

angle ABC = 180°-130°

Therefore, angle 50°

angle EBD = 50° ( Vertically opposite angle)

Now;

angle EBD= angle DEB = 50° ( Base angle of triangle BDE )

angle BDE + angle DEB + angle EBD = 180° ( Sum of interior angle)

angle BDE = 180° -100°

Therefore, angle BDE = 80°.

Now, 80° + 14x + 2 = 180° { being linear pair}

14x = 180°-82°

14x = 98°

$x = \frac{98}{14}$

X = 7°

Hope it helps......

Answer:

$\frac{2}{3}$

Step-by-step explanation:

To determine the scale factor consider the ratio of the image coordinates to the original coordinates, that is

scale factor = $\frac{4}{6}$ = $\frac{6}{9}$ = $\frac{2}{3}$
