Answer:

I don't really know but one triangle is 180 degrees so two added together is 360 degrees...

but ohh I remembered

a=c+d (since a+b=180 and c+d+b=180)

e=g+h (since e+f=180 and g+h+f= 180)

and the fact is that c+d+g+h+b+f=the angle sum of quadrilateral PQRS

a+e+b+f= the angle sum of quadrilateral PQRS (by substitutions)

a+e+b+f=360 (four angles are from one origin so it's 360 degrees )

In order to determine the number of squirrels in a conservation area, a researcher catches, and marks 114 squirrels then release
vodomira [7]

Answer:

456 squirrels

Step-by-step explanation:

We have the following formula:

N = M * C / R

Where "N" is the estimated population size, "M" is the number of individuals already tagged, "C" is the total number of those caught the second time regardless of whether or not they are tagged, and "R" is the total number of tagged recaptured individuals.

Now, replacing we have:

N = 114 * 96/24

N = 456

Therefore, there are approximately 456 squirrels in the conservation area.

(10 points plus 5 and brainliest)!
velikii [3]

Answer:

y = 15x + 200

Step-by-step explanation:

It should be y = 150x + 200 because if you look at the first one, 300x is too big.

You can cross out the last two.

Then you can see the second one also doesn't work.

Cross that one out.

The first choice is the only one.
