From the diagram below, we need to find the hypotenuse, h
By Pythagoras theorem:
h² = 4² + 5²
h² = 16 + 25
h² = 41
h = √41
= 6.4
Sin Theta = Opposite/Hypotenuse
= (-5)/6.4
= -0.781
By Pythagoras theorem:
h² = 4² + 5²
h² = 16 + 25
h² = 41
h = √41
= 6.4
Sin Theta = Opposite/Hypotenuse
= (-5)/6.4
= -0.781
