Which of the following equations could be used to solve for x in the triangle shown?

Answer:
sin 37 = 13/x
Step-by-step explanation:
In any right angle triangle sine of an angle = Opposite side/Hypotenuse
From the given figure sin 37 = 13/x is the equation from which we can get the measurement of x.
sin 37 = 13/x
x = 13/sin 37 = 13/0.6018 = 21.60
