45agon 78agon 86agon.
after like 12 sides you just add agon after the number.
heptacontaoctagon
An acute angle.
sqrt(78) = √78. There is no simplification.
90-78= 12 degrees
The diameter will be the circumference of 78 divided by pi
45 + 78 = 123
45% of 78= 45% * 78= 0.45 * 78= 35.1
a - 45 = -78 +45 +45 = -123 a= -123
45 * 78 = 3510
33
45-78*j
78 divided by 45 is 1 with remainder 33.
heptacontaoctagon
If the perimeter of a shape is 78, it means the sum of all its sides is 78 units. To find the measurement of each side, you would need to know the number of sides the shape has. For example, if it is a rectangle with two equal sides and two other sides of different lengths, the measurement of each side would be 78 divided by 2, which is 39 units.
45/78 = (3×15)/(3×26) = 15/26
I would call it a 78-gon. Keep it simple! Not only is the use of long Greek prefices pretentious, you will only annoy the reader who will probably have to consult a dictionary.
45 - 78 + 67 + 1904 + 6879 = -8,883
