Answer:

B

Step-by-step explanation:

SohCahToa

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

opposite is 1

hypotenuse is 3

adjacent is 2 sq rt 2

cos= 2 sqrt 2 / 3

tan= 1 / 2 sq rt 2 which is also eqal to sq rt 2 / 4

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).

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

Hillsdale Orchard's owners decide to plant 30 new Gala apple trees, he needs to pllat 40 new fuji trees so as to maintain the same ratio of Fuji apple trees to Gala apple trees.

An equation is an expression that shows the relationship between two or more numbers and variables.

From the table:

Ratio of Fuji apple trees to Gala apple trees = 160 / 120 = 4/3

Hence, for 30 new galla trees, number of Fuji trees is:

Fuji trees = (4/3) * 30 = 40

The length of the radius of the circle with a central angle measuring 7pi/6 is 4.9cm

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
r = 108/7pi

r = 4.9cm

Answer:

40 degrees

Step-by-step explanation:

if the lines are perpendicular, then they are also sharing the same line so that means, its a simple equation of 180-140=40.

Answer:

The value of angle 2 = 40°

Step-by-step explanation:

Given : angle 1 = 140°

angle 1 + angle 2 = 180° { because they are linear pair }

=> 140 + angle 2 = 180°

=> angle 2 = 180 - 140

=> angle 2 = 40°
