If sin y° = s divided by 8 and tan y° = s divided by t, what is the value of cos y°? 1.) cos y° = 8s
2.) cos y° = 8t
3.) cos y°=t divided by 8
4.) cos y°=8 divided by t

cos y = t/8

Step-by-step explanation:

tan y = (sin y) / (cos y)

Solve for cos y:

cos y = (sin y) / (tan y)

Substitute:

cos y = (s/8) / (s/t)

Multiply by reciprocal:

cos y = (s/8) (t/s)

Simplify:

cos y = t/8

it happens during combustion and impacts the environment because the plants and trees take in that and it can cause them to die.
