Answer:

1. x =8

2. x=9

Step-by-step explanation:

Since these figures are parallelograms, the opposite sides are equal.

1. 6 = 2x-10

Add 10 to each side

6+10 = 2x-10+10

16 = 2x

Divide each side by 2

16/2 = 2x/2

8 =x

2. x+14 =23

Subtract 14 from each side

x+14-14 = 23-14

x = 9

(C)the central angle measure of the sector multiplied by the area of the circle will yield the area of the sector.

(D)the central angle measure of the sector multiplied by the circumference of the circle will yield the area of the sector.

Answer:

(A)the central angle measure of the sector divided by the total angle measure of a circle multiplied by the area of the circle will yield the area of the sector.

Step-by-step explanation:

The area of the shaded sector can be determined using the formula:

$\frac{m\angle ZYX}{360^\circ} \cdot \pi r^2$
