For 9, 4/3 would opposite / adjacent for the reference angle. Then remember your Trig identities

same thing for 10 and 11

From google - ""SOHCAHTOA" is a helpful mnemonic for remembering the definitions of the trigonometric functions sine, cosine, and tangent i.e., sine equals opposite over hypotenuse, cosine equals adjacent over hypotenuse, and tangent equals opposite over adjacent"

your hypotenuse side will always be the side opposite the right angle denoted by the square

hope that helps

but how do I find out what its equal to?

[rich salmon]

Its multiple choice

[white wharf]

am I supposed to solve what the angel of c is equal to and then do something with 4/3?

[rich salmon]

you chose which choice is equal to the given reference angle

[lucid temple]

You don't need to solve to find C
You can look at 4 and 3 in relation to the reference angle
For question 1, the side opposite C has length 4, and the side adjacent to C has length 3. Therefore, 4/3 is opposite/adjacent = tanC. You can repeat this method for other questions

ohh I get it
