How do similar right triangles lead to the definitions of the trigonometric ratios?

The ratio of two sides of one right triangle is the same of the corresponding sides of any its similar triangles.

Call a, b, c the sides of a right triangle and A, B, C the sides of any of its similar triangles.

Then a/b  = A/B, which means that this ratio is a constant.

The same for a/c = A/C, and b/c = B/C.

Even, the same is true for the inverses: b/a = B/A; c/b = C/B, and d/a = C/A.

Then, you can define a function for every one of these ratios. Those functions are the trigonometric functions.

miss Akunina [59]
So a line is 180°
Since it gave you options, the easiest way would be to plug it in (plug and chug)
the answer is 11
first what I did was plug 12 into 5x+10 and then found the answer and then added 58°
the answer of that subtracted from 180
with that I then plugged in 11 for x for 11x+2 = 123
180 - 123 = 57 which is the same answer for the missing angle within the triangle

It is very confusing with negatives so what do I do
Kamila [148]
A lot of people find it easier to visualize what the least to greatest would look like. So imagine a number line that starts (in the middle) at 0. All numbers to the right get GREATER and GREATER. Going for 0 to 1 to 2.... and higher. Going to the left it gets LOWER and LOWER. So, -1 to -2 to -3 and onward. Basically what I'm trying to say is the farther you are to the left the smaller you are. 

Another way you can think of it is you could remove the negative, and put them in order from least to greatest. Then when you add the negative back you would flip the order. So let's do that with our current problem: (Keep in mind that if you do this with sequences that are not all negative numbers you need to make the positive numbers negative. Or you can write out a number line and put all the numbers on it) 

Our Numbers:
-1.639, -7.06, -7.6, -0.6299, -7.0699, -7.399

Remove the Negative Temporarily: 
1.639, 7.06, 7.6, 0.6299, 7.0699, 7.399

Put the numbers in order from least to greatest:
0.6299, 1.639, 7.06, 7.0699, 7.399, 7.6 

Now add the negative sign back: 
-0.6299, -1.639, -7.06, -7.0699, -7.399, -7.6

Now reverse the order to get the correct answer: 
-7.6, -7.399, -7.0699, -7.06, -1.639, -0.6299
