a. Sin L=hyp/opp=KL/KJ=17/15
b. Sec L= adj/hyp=JL/KL=8/17
c. Tan K= opp/adj= JL/KJ=8/15
If you are having trouble with sin cos and adj. Here’s a little help, remember SOH CAH TOA.
SOH= Sin= opp/hyp
CAH= Cos= adj/hyp
TOA= Tan= opp/adj
And then for csc, sec, and cot,remember that they are the opposite of sin, cos,tan.
csc= opposite of sin= hyp/opp
sec=opposite of cos= hyp/adj
cot= opposite of tan= adj/opp
