Answer:

$1.72222\ radians$

Step-by-step explanation:

Given radius $=9$ and arc length $=15.5$ .

$arc\ length=radius\times central\ angle(radians)\\Central\ angle(radians)=\frac{arc\ length}{radius} \\$

$central\ angle=\frac{15.5}{9}=1.72222\ radians$

Answer:

2. Addition property of inequality. You're adding 6x to both sides.

3. 4x = 28

4. 4x/4 = 28/4 Justification: Division property of inequality

You're dividing both sides by 4.

5. x = 7

Hope that helps.

If EF bisects angle CEB, angle CEF=7x + 21 and angle FEB = 10x - 3, find the measure of DEB.

morpeh [17]

Answer: DEb = 26°

Step-by-step explanation:

Given information

CEF = 7x + 21

FEB = 10x - 3

Given expression deducted from the definition of the bisector

FEB = CEF

Substitute values into the expression

10x - 3 = 7x + 21

Subtract 7x on both sides

10x - 3 - 7x = 7x + 21 - 7x

3x - 3 = 21

Add 3 on both sides

3x - 3 + 3 = 21 + 3

3x = 24

Divide 3 on both sides

3x / 3 = 24 / 3

x = 8

Find the sum of the angle of CEF and FEB

7x + 21 + 10x - 3

=7 (8) + 21 + 10 (8) - 3

=56 + 21 + 80 - 3

=77 + 80 - 3

=157 - 3

=154

Subtract 154 from the straight angle

DEB = 180 - 154

$\boxed{DEB = 26}$

Hope this helps!! :)

8^x=2 write down the value of x

e-lub [12.9K]

Answer:

x = $\frac{1}{3}$

Step-by-step explanation:

Using the rule of exponents

$a^m^{n}$ = $a^{mn}$

Note that 8 = 2³ and 2 = $2^{1}$ , then

$(2^3)^{x}$ = $2^{1}$ , that is

$2^{3x}$ = $2^{1}$

Since the bases on both sides are equal, equate the exponents

3x = 1 ( divide both sides by 3 )

x = $\frac{1}{3}$

sladkih [1.3K]

Answer:

343.77°

Step-by-step explanation:

1 radian = $\frac{180}{Pi}$ °

6 radians will be;

6 × $\frac{180}{Pi}$ ° =343.7746771 °

Or 343.77° (rounded up to nearest hundredth)
