Answer:

3240 degrees.

Step-by-step explanation:

Here (as you said), this 20-gon is convex. In the image below, that is #1. One interior angle is 162 degrees. Simply multiply that by 20 to get 3240 degrees as the sum.

Find the distance between the pair of points. Round your answer to the nearest tenth if necessary.

Kaylis [27]

Answer:

The distance between the pair of points is 12.0 (to the nearest tenth)

Step-by-step explanation:

The distance between a pair of points in a coordinate system is found by the formula:

d = $\sqrt({x_2-x_1)^2+(y_2-y_1)^2}$

where, the points are:

$(x_1,y_1)\ and\ (x_2,y_2)$

From the graph,

$(x_1,y_1)=(-6,-2)\\(x_2,y_2)=(2,7)$

Substitute the points into the formula:

$d=\sqrt{(2-(-6)^2+(7-(-2)^2} \\d=\sqrt{(2+6)^2+(7+2)^2} \\d=\sqrt{8^2+9^2} \\d=\sqrt{64+81} \\d=\sqrt{145} \\\d=12.0$
