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

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

the first one, all those points on the line just make a strait line.

you can't solve x because it is 2 linear equation and you only have one equation
