Finding the missing value in a proportion is much like finding the missing value for two equal fractions. Solvency ratios are different than liquidity ratios, which emphasize short-term stability as opposed to long-term stability. To solve the similarity problem, you usually need to create a proportion and solve for the unknown side. Trigonometric ratios of 90 degree plus theta. How high is the lamp post? Definition of Trigonometric Ratios In a right triangle, the six trigonometric ratios; the sine ratio, the cosine ratio, the tangent ratio, the cosecant ratio, the secant ratio and the cotangent ratio are defined as follows: 1 - The sine of angle A = sin (A) = side opposite angle A / hypotenuse = a / c You can use a ratio to solve problems by setting up a proportion equation — that is, an equation involving two ratios. In the second step we need to divide and simplify to get the value of the unknown variable. Some other equal ratios: 3:6 = 12:24 = 6:12 = 15:30 . Math Games and Activities.
