Answer:

x= 6

Step-by-step explanation:

You need to set up a proportion

12/8 = 9/x

Then you do Cross Product Property

8*9=72

12*x=12x

12x=72

divide 72 by 12

72/12=6

x=6

Answer:

Step-by-step explanation:

The ratios of corresponding sides are equal, that is

$\frac{XZ}{DF}$ = $\frac{XY}{DE}$ , that is

$\frac{12}{8}$ = $\frac{9}{x}$ ( cross- multiply )

12x = 72 ( divide both sides by 12 )

x = 6

x = DE = 6 → A

Find the arc length of the partial circle. length is 1. **See attached photo**

KatRina [158]

Arc length of the quarter circle is 1.57 units.

Solution:

Radius of the quarter circle = 1

Center angle (θ) = 90°

To find the arc length of the quarter circle:

$$\text{Arc length}=2 \pi r\left(\frac{\theta}{360^\circ}\right)$

$$=2 \times 3.14 \times 1\left(\frac{90^\circ}{360^\circ}\right)$

$$=2 \times 3.14 \times 1\left(\frac{1}{4}\right)$

Arc length = 1.57 units

Arc length of the quarter circle is 1.57 units.
