Answer: The correct option is the last option or option 4
Step-by-step explanation:
Looking at the right angle triangle and considering angle 30 as the base angle,
Opposite side = 5
Adjacent side = is unknown
Hypotenuse is the longest side ant it is equal to x
To find x, we will use trigonometric ratio
Sin# = opposite side / hypotenuse
# is the angle of reference or the base angle. This means that our approach changes with the angle we intend to use as the reference or base angle. In this case,
# = 30 degrees
Sin 30 = 5/x
x = 5/sin 30
So the correct option is the last option or option 4
