Answer :
The trigonometric expression that can be used to find the value of x is tan(x) = 12/x
How to determine the trigonometric expression?
From the question, we have the following parameters:
- Vertical Leg = x
- Base length = 12
- Angle at the vertical side = 25 degrees
The measure of x is then calculated using the following tangent ratio
tan(x) = Base length/Vertical leg
Substitute known values
tan(x) = 12/x
Hence, the trigonometric expression that can be used to find the value of x is tan(x) = 12/x
