How do you find trigonometric ratios of angles greater than 90 degrees?
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
How do you 'find the ratio of its length to its perimeter?
To find the ratio of the length of a shape to its perimeter, you would divide the length by the perimeter. For example, if the length of a rectangle is 4 units and its perimeter is 12 units, the ratio would be 4/12 or 1/3. This ratio represents the proportion of the length to the total distance around the shape.
How do you find the point that divides a line segment according to a given ratio?
-- ADD the two numbers in the ratio.-- Then divide the line segment into that many equal pieces.-- From one end, count off a number of pieces equal to either number in the ratio.-- At the point after that many pieces, the two parts of the line segment on either sideof it are in the desired ratio.
What is the ratio of 2 to 5 of 40?
The ratio of 2 to 5 is typically written as 2:5. To find the ratio of 2 to 5 of 40, you would first calculate 2/5, which equals 0.4. Then, you would multiply 0.4 by 40 to find the ratio of 2 to 5 of 40, which is 16.
How do you find the ratio of 800 and 640?
you would want to find a common denominator -- in this case 160 is the largest common denominator 800/160=5 640/160=4 therefore the ratio would be 5:4 (said "5 to 4")
