There are six sides Because First, the number of sides and the number of interior angles, both are the same To find the sum of all internal angles, you use the formula: (n-2)180=z where n is the number of sides or internal angles, and z is the angle sum. the letters can be anything so now, if one interior angle is 120 degrees, then you get the total angle sum by multiplying 120 by n so just write the equation, and replace z (angle sum) with 120n (n-2)180=120n Solve it in any way you like 180n-120n=360 60n=360 n=6 there are six sides and internal angles! This is a hexagon. FYI, a hexagon's internal angles add up to 120*6=720 degrees
absolutely can not be written in the form , the value you have given is a approximate value of . The problem may want to tell you any irrational number can be approximately represented by a rational number.
