Cos(90 - x) = sin(x) so cos2(90 - x) = sin2(x)
88 x 90 = 7,920
X + 35 = 90, therefore X = 90 - 35, so X = 55.
Pairs of positive integer factors of 90 are:1 x 90 = 902 x 45 = 903 x 30 = 905 x 18 = 906 x 15 = 909 x 10 = 90And their reverses. Therefore, the positive integer factors of 90 are: 1 2 3 5 6 9 10 15 18 30 45 90.
3 x 5 = 15 15 x 6 = 90 Answer: 90
345678
The answer is: 347,247
345678
he had 345678 children
90 x 1 = 90 10 x 9 = 90 45 x 2 = 90 30 x 3 = 90 18 x 5 = 90 15 x 6 = 90
93 x 90 x 90 x 80= 8370 x 90 x 80= 753,300 x 80= 60,264,000The answer is 60,264,000.
The first ten positive integer multiples of 90 are: 1 x 90 = 90 2 x 90 = 180 3 x 90 = 270 4 x 90 = 360 5 x 90 = 450 6 x 90 = 540 7 x 90 = 630 8 x 90 = 720 9 x 90 = 810 10 x 90 = 900
90 = 1 x 90 90 = 2 x 45 90 = 3 x 30 90 = 5 x 18 90 = 6 x 15 90 = 9 x 10
9 x 10 = 90 or 15 x 6 = 90 or 30 x 3 = 90 0r 45 x 2 = 90 3 x 30 = 90
The first five positive integer multiples of 90 are: 1 x 90 = 90 2 x 90 = 180 3 x 90 = 270 4 x 90 = 360 5 x 90 = 450
Cos(90 - x) = sin(x) so cos2(90 - x) = sin2(x)
90 = x * 32 90/32 = x x = 281.25%
