Find the measure of the interior angles of the following regular polygons: a triangle, a quadrilateral, a pentagon, an octagon,
kvasek [131]

Answer

Triangle  = 60° ; Quadrilateral  = 90° ; Pentagon  = 108° ; Octagon  = 135° ;

Decagon  = 144° ; 30 -gon  = 168° ; 50 -gon  = 172.8° ; 100 -gon =176.4°

Step-by-step explanation:

You follow the equation (N-2)*180, then divide the answer with the the number of sides. Example for Triangle: (N-2)*180=(3-2)*180=(1)*180=180 then divide by 3 because in a triangle there are 3 sides. 180/3=60.

10 < –2b or 2b + 3 > 11
Zinaida [17]
<span>10 < –2b or 2b + 3 > 11 represents 2 different sets of numbers.

</span><span>10 < –2b can be reduced by dividing both sides by -2; you must then reverse the direction of the < sign:  -5 > b, which is the interval b < -5:  (-infinity, -5).

</span>2b + 3 > 11 reduces to 2b > 8, which in turn reduces to b > 4:  (4, infinity).

It may be helpful to graph these sets.

If you really do mean   "<span>10 < –2b or 2b + 3 > 11," then the "solution" is made up of two sub-intervals:  b < -5 and b > 4.
