Because one of the angles formed equals 20°, the other angles must measure 20°, 160°, and 160°
Therefore, the product of all four degree measures \(= (20)^2(i 60)^2 = 400 x 25,600 = 10,240,000\). This is very close to 10,000,000, or \(1 x 10^7\).

How would you do this without a calculator. Eg, how would you figure out the number of zeros and what the first digit of the answer would be? I know there is a method for figuring that out quickly by hand, but I don't know it
