Question

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

Answer 1

sin ( theta ) = opposite / hypotenuse
sin ( 37° ) = 13 / x

Answer 2

sin 37 = 13/x

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
