Answer:
sin(0) = (-2 sqrt of 70) / 19
Explanation:
Cos = adjacent / hypotenuse
Sin = opposite / hypotenuse
so, using the pythagorean theorem ( a^2 + b^2 = c^2
opp^2 = adj^2 - hyp^2
opp^2 = 9^2 - 19^2
opp^2 = 81 - 361
opp = sqrt of -280
sqrt of 280 can be rewritten as -2 sqrt 70
So, opp = -2 sqrt 70
Sin = opp / hyp
Sin = (-2 sqrt 70) / (19)
