The trigonometric expression that it is used to find the value of x is tan(x) = [tex]\frac{12}{x}[/tex]
Trigonometry ('triangle', or 'measure') is the branch of mathematics that studies relationships between side lengths or the angles of the triangles
by the question, we have the following parameters:
Vertical Leg = x
Base length = 12
Angle at the vertical side = 25 degrees
The measure of the x is then calculated using the following tangent ratio
tan(x) = Base length / Vertical leg
Substitute known values
tan(x) = 12/x
So, the trigonometric expression that it is be used for find the value of x is tan(x) = 12/x
