Answer:

A= 21.65063509

Step-by-step explanation:

triangle area is =base*hight/2

Because we have a right triangle we can apply the trigonometric functions

sin30 =base/hypothenuse = base/10

cos 30 = hight/hypothenuse =hight/10

sin30 = base /10  ; multiply both sides by 10

base = 10*sin30

cos 30 = hight /10 ; multiply both sides by 10

hight = 10 cos 30

A= 10*sin30*10*cos30/2 =

      100*sin 30*cos 30/2=

            50*sin30*cos30 = ; use calculator make sure is set up in degrees

A= 21.65063509

Find the value of the arc x.
julsineya [31]

Answer:

216°

Step-by-step explanation:

Both chords are the same length, so the left and right arcs are both 72°.  The whole circle is 360°, so:

72° + 72° + x = 360°

x = 216°

SOMEONE HELP PLEASE!!!
Oliga [24]

Answer:

x = 2 1/3

y = 14 / (2 1/3) = 14 / (7/3) = 14*3/7 = 42/7 = 6

y = 6

x = 4 1/5

y = 14 / (4 1/5) = 14 / (21/5) = 14*5/21 = 70/21 = 3 7/21 = 3 1/3

y = 3 1/3

x = 7/6

y = 14 / (7/6) = 14*6 / 7 = 12

y = 12

Calculate the gross pay per paycheck for C. D. Edgeling, who makes an annual salary of $30,000 and is paid biweekly.?
son4ous [18]
If you get paid a salary, and you want to know the weekly amount of pay, you need to determine the number of weeks in a year. Sure, you might say "But that's 52 weeks". Wrong. There are 365.25 days in a year (364 but then an extra day every 4th or leap year) There are 7 days in a week. So the number of weeks in a year is: 365.25/7 = 52.1785715285714 weeks This is usually rounded to 2<span>decimal places: 52.18 weeks Therefore, for a salary of 60 000 p.a., </span>

true or fales: a significant correlation indicates that changes in the values of one factie cause changes in the values of a sec
natka813 [3]

Answer:

A significant correlation means that there is a significant (in a statistical point of view) correlation between two things.

Then a significant correlation means that we have a (measurable) correlation between the variables in our experiment.

Now, the factors are the variables that experimenters control during an experiment in order to determine their effect on the response variable, then having a positive correlation between two factors, means that when we change one, the other is also affected by the change in the first one.

Then the statement is true.
