Given 2 intersecting chords, then

The product of the parts of one chord is equal to the product of the parts of the other chord, that is

27x = 9 × 21 = 189 ( divide both sides by 27 )

Eddi Din [679]

Answer:

- For the statement $-3x=24$ , the reason is: Subtraction property of Equality

- For the statement $x=-8$ , the reason is: Division property of Equality.

- For the statement $m\angle B=-6(-8)-39$ , the reason is: Substitution property of Equality.

Step-by-step explanation:

The missing pictures are attached.

We must remember that:

- The Subtraction property of Equality states that:

$If\ a=b,\ then\ a+c=b+c$

- The Division property of Equality states that:

$If\ a=b,\ then\ \frac{a}{c}=\frac{b}{c}$

- The Substitution property of Equality states that:

$If\ a=b,\ then\ b\ can\ replace\ a$

Knowing this properties we can identify the missing reasons that correctly complete the proof.

- For the statement $-3x=24$ , the reason is:

Subtraction property of Equality

(Because it is obtained by subtracting 66 from both sides of $-3x+66=90$ )

- For the statement $x=-8$ , the reason is:

Division property of Equality

(Because it is obtained by dividing both sides of $-3x=24$ by -3)

- For the statement $m\angle B=-6(-8)-39$ , the reason is:

Substitution property of Equality

(Because it is obtained by substituting the value of "x" into $m\angle B=-6x-39$ )
