Step-by-step explanation:
Draw a right triangle with horizontal base length 2, vertical length 3.
Use pythagorean thm to find length of hypotenuse:
Now use SOH CAH TOA to find correct trig ratios:
The opposite side is always the vertical side ----> 3
The adjacent side is always the horizontal side ---> 2
SOH ---> sin = opp/hyp
CAH ----> cos = adj/hyp
TOA -----> tan = opp/adj
