Best ResponseYou've already chosen the best response.2There are three basic ratios. Sin ratio, cos ratio, tan ratio. you have to remember these.. Not them down somewhere.

Best ResponseYou've already chosen the best response.2Now these are the three sides. now it depends upon the question which two ratio you have to use.. you have to judge it by yourself.

Best ResponseYou've already chosen the best response.2Now in your question.. you are given hypotenuse and you have to find the opposite side.. so u will be using sin ratio.

Best ResponseYou've already chosen the best response.0Ok, so the basic idea is that if you have a right angle, and You know the second angle, you know the ratio of the two sides. Now all of the trig functions essentially take in an angle, and out put a ratio.

Best ResponseYou've already chosen the best response.0For triangle similarity, we can prove that two triangles are similar given certain info (SAS, AA, SSS, etc). But if they are similar, then how can we figure out the side lengths they have?

inkyvoyd

Best ResponseYou've already chosen the best response.0The answer is that we use trigonometry. The basic idea of trig is that in a right triangle where we know all the degree measures, we can determine the ratio between the sides.
