Background: I have just about high school knowledge of math, I am sorry if this is a stupid question.
In school, we learned that when transposing, this:
y = x * 3
x = y / 3
I was reading up on trigonometry, and as I was reading the following:
If we look at the general definition -
we see that there are three variables: the measure of the angle x, and the lengths of the two sides (Opposite and Hypotenuse). So if we have any two of them, we can find the third.
In the figure above, click 'reset'. Imagine we didn't know the length of the hypotenuse H. We know that the sine of A (60°) is the opposite side (26) divided by H.
From our calculator we find that sin60 is 0.866, so we can write
which comes out to 30.02
As per the rules of transposition (that I probably got wrong), isn't it supposed to read
H = 26 * 0.866
What am I missing?
