Find the value of x

A. 12
B. 6
C. 10

Answers

Answer:

x = 12

Step-by-step explanation:

Let's find the measure of major arc MNB:

360 - arc MB = major arc MNB

Now, let's plug in what we know:

360 - (80 + 60) = major arc MNB

Next, combine like terms, and replace "major arc MNB" with "x."

360 - 140 = x

220 = x

Now, we know that the measure of major arc MNB equals 220 degrees.

Angle MLB is going to be double the measure of major arc MNB, so let's set up an equation for this situation:

2(Angle MLB) = major arc MNB

Now, let's plug in what we know:

2(9x + 2) = 220

Finally, let's solve for x:

18x + 4 = 220

18x = 216

x = 12

Arithmetic with common difference of [tex]\sf \frac{1}{3}[/tex]

Step-by-step explanation:

[tex]\textsf{Given sequence}=4, \dfrac{13}{3}, \dfrac{14}{3}, 5, \dfrac{16}{3},...[/tex]

If a sequence is arithmetic, the difference between consecutive terms is the same (this is called the common difference).

If a sequence is geometric, the ratio between consecutive terms is the same (this is called the common ratio).

[tex]\sf 4\quad \overset{+\frac{1}{3}}{\longrightarrow}\quad\dfrac{13}{3}\quad \overset{+\frac{1}{3}}{\longrightarrow}\quad \dfrac{14}{3}\quad \overset{+\frac{1}{3}}{\longrightarrow}\quad 5\quad \overset{+\frac{1}{3}}{\longrightarrow}\quad \dfrac{16}{3}[/tex]

As the difference between consecutive terms is [tex]\sf \frac{1}{3}[/tex] then the sequence is arithmetic with common difference of [tex]\sf \frac{1}{3}[/tex]

General form of an arithmetic sequence: [tex]\sf a_n=a+(n-1)d[/tex]

where:

[tex]\sf a_n[/tex] is the nth terma is the first termd is the common difference between terms

Given:

a = 4[tex]\sf d=\dfrac{1}{3}[/tex]

So the formula for the nth term of this sequence is:

The formula for calculating the legnth of an arc is expressed as:

L = rtheta

r is the radius

Theta is the subtended angle

Given the following

18 = r(7pi/6)
7pi r = 18 * 6

7pi r = 108

Answer:

B

Step-by-step explanation:

Sin opposite/hypotenuse

Cos adjacent/hypotenuse

Tan opposite/adjacent

so if sin is 1/3 the opposite is 1 and the hypotenuse is 3

to find cos do a^2+b^2=c^2

1^2 + x^2 = 3^2

1+x^2=9

subtract 1 from both sides

x^2=8

do the square root x=2 sq root 2

that leaves u with
