90/2 = 45/1
subtract 90 from it and find the trig ratio of that and it will be equal to the trig ratio that is over 90 degrees
The ratio of 90 to 18 is written as 90/18
In order to determine if two sets of numbers are proportional, you need to compare their ratios. For 7 and 9, the ratio is 7/9, which simplifies to 0.777. For 70 and 90, the ratio is 70/90, which simplifies to 0.778. Since these two ratios are not equal, 7 and 9 are not proportional to 70 and 90.
The ratio of 90 to 300 can be simplified by dividing both numbers by their greatest common divisor, which is 30. This gives us a simplified ratio of 3 to 10. Therefore, the ratio of 90 to 300 is 3:10.
It is in the ratio of: 90 210
