Answer:
The answer to your question is csc Ф = [tex]\frac{-5}{4}[/tex]
Step-by-step explanation:
Process
1.- Determine the sign
We must determine csc Ф in the forth quadrangle, here csc is negative.
2.- Determine the hypotenuse
c² = a² + b²
c² = 3² + (-4)²
c² = 9 + 16
c² = 25
c = 5
3.- Determine csc Ф
csc Ф = [tex]\frac{hypotenuse}{opposite side}[/tex]
csc Ф = [tex]\frac{5}{-4}[/tex] = [tex]\frac{-5}{4}[/tex]
