Answer 1

sec

Answer 2

do you remember what sin means?

Answer 3

yes

Answer 4

ok so sin is opposite/hypotenuse

Answer 5

do you know what theta is

Answer 6

Do you know which is opposite and which is hypotenuse?

Answer 7

yes

Answer 8

correct

Answer 9

Now that you know which legs are which value, can you plug them into sin=O/H?

Answer 10

so its 84 over 85 right

Answer 11

Yes but your final statement will be \[\sin \theta = \frac{ 84 }{ 85 }\]
or
\[\sin A = \frac{ 84 }{ 85 }\]

Answer 12

theyre both the same, but if i didnt know you were looking for A i wouldnt know what angle was theta.

Answer 13

but theta just means the desired angle

Answer 14

does that help?

Answer 15

a little

Answer 16

S-O-H,C-A-H,T-O-A, these are all 3 functions. Just say it like Soh-Cah-Toa. to remember
