Question

Can someone help me with DEPRECATED Trigonometry? I think I found out how to solve those angular problems, but I'm not quite sure

Answer 1

Sin = opposite over hypotenuse, correct? so it would be AC over AB?

Answer 2

you are right

Answer 3

i have never heard of "depreciated" trigonometry before
what does that mean?

Answer 4

Oh.. it was just the name on the course... I go through khan academy when I'm having a bit of struggle on the course... https://www.khanacademy.org/partner-content/nasa/measuringuniverse/measure_the_solarsystem/a/a-flat-earth

Answer 5

What's the numerical value of your "AC over AB?"

Answer 6

I got \[5 \over 13\] because the opposite was AC = 5 and my adjacent was BC = 12
