Question

If sin y degree = s/8 and tan y degree =s/t what is the value of cos y degree

Answer 1

Answer:

cos y= t/8

Step-by-step explanation:

we can proceed by using the SOH CAH TOA method

$=sin (y)= \frac{opp}{hyp}= \frac{s}{8} \\\\=tan (y)= \frac{opp}{adj}= \frac{s}{t}$

from the two functions above we can see that

1. opp= s

2. hyp= 8

3. adj= t

hence

$cos(y)= \frac{adj}{hyp}= \frac{t}{8}$
