You spell the numbers as follows: 50 is spelled "fifty," 60 is "sixty," 70 is "seventy," 80 is "eighty," and 90 is "ninety." Each of these words represents the respective numerical value in written form.
In French, the numbers are spelled as follows: 20 is "vingt," 30 is "trente," 40 is "quarante," 50 is "cinquante," 60 is "soixante," 70 is "soixante-dix," 80 is "quatre-vingts," 90 is "quatre-vingt-dix," and 100 is "cent."
Supplementary angles are two angles that add up to 180 degrees. Among the pairs you listed, 70 and 110 are supplementary (70 + 110 = 180), and 20 and 80 are also supplementary (20 + 80 = 100). The pairs 30 and 60 (30 + 60 = 90) and 50 and 50 (50 + 50 = 100) are not supplementary.
50, 60, 70, 80, 90
50, 60, 70, 80, 90, and 100.
The result of the equation - 130 plus 80 plus 60 plus 70, is found as follows;130 + 80 + 60 + 70= ( 130 + 80 ) + 60 + 70= 210 + ( 60 + 70 )= 210 + 130= 340Answer = 340
Take your pick; 10 and 20, 10 and 30, 10 and 40, 10 and 50, 10 and 60, 10 and 70, 10 and 80, 10 and 90, 20 and 30, 20 and 50, 20 and 70, 20 and 90, 30 and 40, 30 and 50, 30 and 70, 30 and 80, 40 and 50, 40 and 70, 40 and 90, 50 and 60, 50 and 70, 50 and 80 50 and 90, 60 and 70, 70 and 80, 70 and 90, 80 and 90.
