Answer:

x= 19

Step-by-step explanation:

Is given that the <u>triangles are congruent</u> so the corresponding sides are congruent as well.

Also congruent sides are equal in measure so we use the given picture to write the equality.

2x -1 = 37, add 1 to both sides

2x = 38 , divide both sides by 2

x = 19

Please help and thank you

Answer:

Step-by-step explanation:

Let's see how well I can explain this. $\frac{\pi}{6}$ is the same as a 30 degree angle which is in quadrant 1. If you picture the unit circle, right in the center of it is the origin. If you draw a straight line from 30 degrees and through the center (the origin), you will automatically "connect" with the reference angle of 30 (this is true for ALL angles on the unit circle). This puts us in quadrant 3. In quadrant 3, x is negative and so is y. So the terminal point of the reference angle for 30 degrees has the same exact values, but both of them are negative (again, because both x and y are negative in quadrant 3). I can't see your choices but the one you want looks like this:

$(-\frac{\sqrt{3} }{2},-\frac{1}{2})$

The value of y varies directly as the square of x and y=27 when x=9. Find the equation represents this relationship. Report the

Answer:

The relation between x and y is

$y=\frac13 x^2$

Step-by-step explanation:

Given that,

The value of y varies directly as the square of x.

$y\propto x^2$

$\Rightarrow y=rx^2$

where r is constant of proportional.

Given that,

y= 27 and x=9

Plug y= 27 and x=9 in above relation

$y=rx^2$

$\therefore 27=r(9)^2$

$\Rightarrow 27 = r.81$

$\Rightarrow r=\frac{27}{81}$

$\Rightarrow r=\frac{1}{3}$

The relation between x and y is

$y=\frac13 x^2$

Answer:

The solution can be defined as follows:

Step-by-step explanation:

Wetland Percentage:

$0] 9\\\\1] None\\\\2] 0 4 7\\\\3] 0 3 5 5 5 7 8\\\\4] 2 2 5 5 8\\\\5] 0 0 1 1 5 9 9\\\\6] 0 8\\\\7] 1\\\\8] 7 7 9\\\\9] 0\\$

These details are very symmetrical, perhaps pretty biased.
There might be a gap whereby shows that none of the 48 lowest states have lost 10 to 19% of all its wetlands.
These statistics were distributed between 20% and 60%.
