What is the sum of the measures of the interior angles of a 19-gon?

S = (19 - 2) * 180 = 3060°

If the sum of the measures of a polygon is 1800°, how many sides does it have?

1800=(n-2)*180 ... n = 12

What is the measure of each interior angle of a regular decagon?

((10-2)*180)/10 = 144°

What is the sum of the exterior angles of a 25-gon?

Sum of exterior is ALWAYS 360°

What is the measure of each exterior angle of a regular decagon?

360/10 = 36°

Find the value of x.

Sum = 900, then x = 121

Find the value of x.

Sum = 540, then x = 18

Find the value of x.

((8-2)*180)/8 = 135 ... 16x+23=135 ... x = 7

Find the value of x.

(add all & set equal to 360) x = 13

Given the figure is a parallelogram, find the measure of angle R.

m∠R=135

Given the figure is a parallelogram, find the measure of angle D.

m∠D = 110

Given parallelogram YVWX, find m∠VXW.

x+60+52=180; x = 68

Given parallogram JKLM and that KM = 23.4, find the length of YM.

(diagonals bisect each other) 23.4/2 = 11.7

Given parallelogram WXUV, solve for x.

x + 1 = 7; x = 6

Given parallelogram LMJK, solve for x.

2(50x)+2(130x)=360; x = 1

Given parallelogram STUR, solve for x.

2x+15 = x+15 ; x = 0
