Answer:
5.1cm
Step-by-step explanation:
volume of hemisphere = 1.07cm³
9.2-1.07 = 8.13
volume of cylinders = 8.13cm³
height of cylinder = 4.04cm
total height of gizmo = 4.04+0.8=4.84
4.84/sin(72) = 5.1cm
Answer:
80 degrees
Step-by-step explanation:
The amount all the angles in a triangle always add up to 180.
6x+4x+8x = 180
18x=180
x=10
The largest angle is 8x so 8*10 = 80

Answer:
Step-by-step explanation:
Irregular polygons are polygons in which the sides are not equal to each other. This also means that the internal angles are not equal to each other. Similar polygons, on the other hand, are polygons with equal corresponding angles which makes the sides proportional to each other correspondingly. The answer then is C.
