Hi there ! \(๑╹◡╹๑)ﾉ♬

Answer: $\blue{ \boxed{ \bf {9a}^{2} - 12a + 4 } }$

Step-by-step explanation:

$\bf (3a - 2)^{2} =$

$\bf (3a - 2) \times (3a - 2) =$

$\bf 3a \times 3a - 3a \times 2 - 2 \times 3a - 2 \times ( - 2) =$

$\bf {9a}^{2} - 6a - 6a + 4 =$

$\red{ \boxed{ \bf {9a}^{2} - 12a + 4 } }$

Use the Pythagorean theorem for this. (a^2+b^2=c^2)

a=9, b=12, c=x

9^2+12^2=c^2
81 + 144 = c^2
225 = c^2
c =15

the answer is c

liberstina [14]

Answer:

(2) a rotation by $180^{0}$ about the intersection of the lines creating the vertical angles.

Step-by-step explanation:

Rigid motion are a set of transformation procedure to change the dimension, orientation or size of a given figure or shape. It involves rotation, translation, reflection and dilation.

Vertical angles are formed when two straight lines intersect to form angles. But two opposite angles called vertical angles are equal. To prove that vertical angles are equal; a rotation by $180^{0}$ about the intersection of the lines creating the vertical angles is required.
