20 is the answer A+
A little less than 1/4 of an acre.
A - 20° = 90° - A ∴ 2A = 110° ∴ A = 55°
110 feet x 110 feet = 12,100 square feet (this, incidentally, is a very large room).
Supplementary angle means that the sum of two angles should be 180o Let the required supplement be x x+110=180 x=180-110 x=70 Hence the required supplement of the 110 angle is 70 degree.
20 is the answer A+
110 x 90 = 9900
2 x 3 x 3 x 5 = 90 2 x 5 x 11 = 110
110 = 2 x 5 x 11
110% of 90 = 99
What is the product of 110 and 90
110% of 90 = 99
If: x+x2 = 110 then x = 10 which is the solution
90 = 100% 25 = X% X = 25x100 ÷ 90 X = 27.777777777777%
-20
-11 x -10 = 110 + -20 = 90
