## anonymous one year ago Help please.How do you decide which trigonometric ratio to use? How do you know which side is the opposite, adjacent, or hypotenuse based on the given information in each problem? Be specific in your explanation.

1. Nnesha

|dw:1441746818292:dw|

2. Nnesha

hypotenuse is the longest leg of right triangle adjacent and opposite sides depends on the angle you are looking at adjacent: the side the touche the angle (theta)

3. Jhannybean

SOHCAHTOA $\sf sin (\theta) = \frac{opp}{hyp} = SOH$$\sf cos(\theta) = \frac{adj} {hyp} = CAH$$\sf tan(\theta) = \frac{opp}{adj} = TOA$

4. Nnesha

like for this angle x |dw:1441747318305:dw| $\rm sin \rm \theta = \frac{ opposite }{ hypotenuse }~~~~ \cos \theta = \frac{ adjacent }{ hypotenuse } ~~\tan \theta = \frac{ opposite }{ adjacent }$

5. Nnesha

this is for practice |dw:1441747767631:dw|which ratio would you use ?

6. Nnesha

given is adjacent side and we have to find x (hyp side)
