A right angle triangle has three sides and three interior angles one of which is 90 degrees. The names of its sides are the adjacent the opposite and the hypotenuse and using the 3 trig ratios we can find the interior angles or lengths of the sides depending on the information given.
Tangent angle = opposite/adjacent
Sine angle = opposite/hypotenuse
Cosine angle = adjacent/hypotenuse
If we are given the lengths of 2 sides we can work out the angles with the above ratios.
If we are given a length and an angle we can work out the lengths of the other 2 sides by rearranging the above ratios.

What is the Equivalent ratios for 3 to 3 12?
yes
Why are all aspect ratios identified as something to 1 or perhaps even recorded as a decimal value?
It allows the ratios to be compared more easily. But they are NOT all defined as unit ratios. My monitor has an aspect ratios of 4:3 or 16:9.
How do you solve ratios?
You do not solve ratios: they are simply a form of numbers. There may be questions whose solutions require you to work with ratios but there the answer will depend on the sort of question you have to deal with.
What are two ratios that are equal to each other?
Ratios that are equal to each other can be 3/4=75/100 or 1/4=25/100
Does tan 45 degrees and sin 45 degrees equal trig values?
They are both trig values, but not equal. Tan 45 is 1 and sin 45 is 0.7071
What are trig ratios?
Trig ratios or to give them their proper name are trigonometrical rations applicable to right angle triangles and they are tangent ratio, sine ratio and cosine ratio.
Can trig ratios only be used on right triangles?
Yes
What are trig?
Trig ratios or to give them their proper name are trigonometrical rations applicable to right angle triangles and they are tangent ratio, sine ratio and cosine ratio.
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
What is the unit of cosine25?
Since trig functions are no more than ratios between the sides, it is unitless.
Using a ruler how to measure an angle?
You cannot measure an angle using a ruler.
What are the 3 basic trig ratios and how do they work?
The three basic ratios are sine, cosine and tangent.In a right angled triangle,the sine of an angle is the ratio of the lengths of the side opposite the angle and the hypotenuse;the cosine of an angle is the ratio of the lengths of the side adjacent to the angle and the hypotenuse;the tangent of an angle is the ratio of the lengths of the side opposite the angle and the the side adjacent to the angle.
How do astronomers use trig in there work?
spherical trig look it up its way confusing
Do you have to know three side lengths of a right triangle before you can use trig ratios to find the measure of an acute angle?

Why is calculus important to trigonometry?
In advanced mathematics, familiar trigonometric ratios such as sine, cosine or tan are defined as infinite series. For example, sin(x) = x - x3/3! + x5/5! - ... Such series are used to calculate trig ratios and the proof of their their convergence to a specific value depends on calculus.
What are 3 types of ratios?
1 - Activity Ratios 2 - Liquidity ratios 3 - Profitability ratios
How can trigonometric ratios be used to find the area of a triangle?
By themselves, they cannot. Two similar triangles have the same angels and so they have the same trig ratios. You need to know the length of at least one side to determine the area.
