Answer:
Step-by-step explanation:
That is not a parallelogram. It has more than four sides.
Area of the white part of the figure is 4×20 = 80 m²
If you expand the figure to include the white part, its area is 9×23 = 207 m².
Green area = 207-80 = 127 m²
Answer:
terminating
Step-by-step explanation:
-128 / 5 = -25.6
-25/6 is terminating because it has an end. a repeating decimal on the other hand goes on forever, like 3.33333...
Answer: either of two angles whose sum is 180°.
Step-by-step explanation:
Answer: 66 degrees
Step-by-step explanation:
Sum of the angle measures is 180, so:
71 + x + 49 + x + 72 = 180
2x + 192 = 180
2x = -12
x = -6
Meaning the measure of angle A = -6 + 72 = 66 deg.
