Answer 2

\[\sin\theta = \dfrac{Opp}{Hyp}\]
\[\tan\theta = \dfrac{Opp}{Adj}\]

Answer 3

SOH CAH TOA

:)

Answer 4

Here, \[\sin y^\text o = \dfrac{Opp}{Hyp} = \dfrac{9}{c}\]
\[\tan y^\text o = \dfrac{Opp}{Adj}=\dfrac{9}{d}\]

Answer 5

oh is it B then?

Answer 6

Right.

Answer 7

thanks

Answer 8

No problem
