The trigonometric expression that represents the value of x is sin⁻¹(3/5), which is equal to 36.87°.
What are trigonometric expressions?
Trigonometric expressions are ratios of the sides of a right triangle.
How to solve the question?
In the question, we are asked to write the trigonometric expression expressing the value of x.
We know that in the given right triangle,
sin x = 3/5 {∵ sin θ = perpendicular/hypotenuse}
Therefore, we can write x = sin ⁻¹ (3/5).
or, x = 36.87°.
Thus, the trigonometric expression that represents the value of x is sin⁻¹(3/5), which is equal to 36.87°.
