Answer:

156

Step-by-step explanation:

Each triangle has an angle sum of 180 degrees, so the sum of the interior angles of the 15-gon must be (n-2) 13 × 180 = 2340 degrees. Since the 15-gon is regular, this total is shared equally among the 15 interior angles. Each interior angle must have a measure of 2340 ÷ 15 = 156 degrees.

Answer:

<h2>The range is the simplest measure of variability to compute. The standard deviation can be an effective tool for teachers. The standarddeviation can be useful in analyzing class room test results. A large standarddeviation might tell a teacher the class grades were spead a great distance from the mean.</h2>

Find the distance between R(-5,-3) and S(4,-2).

harina [27]

Answer:

√106

Step-by-step explanation:

to calculate the distance between two points on an xoy plane you use the formula

√(x2-x1)²+(y2-y1)²

in this case x1 is -5,x2 is 4,y1 is -3 and y2 is -2 therefore the solution will be

√(4-(-5)²+(-2-3)²

√(4+5)²+(-5)²

√(9)²+(-5)²

√81+25

√106

I hope this helps
