tan(x)=sqrt(3)
0<=x<=360

Anzas said:because the whole point of the question is using trigonometric identities to solve it (believe me i would be happy to do the arctan and get it over with )

To solve for angle X, you will need to use trigonometric identities and properties to manipulate the equations and isolate X. It may also be helpful to draw a triangle and label the sides and angles according to the given information.
Sin(x/2) and Tan(x) are related through the half-angle identity for tangent, which states that Tan(x/2) = Sin(x)/(1+Cos(x)). This can be derived using the double-angle formula for tangent.
In order to solve for angle X, you will need to have at least two equations. In this case, you have two equations (Sin(x/2)=1/2 and Tan(x)=sqrt(3)), which means you can use algebra and trigonometric identities to solve for X.
The given values represent the sine and tangent of angle X. These values can be used to find the exact value of angle X, as well as the coordinates of a point on the unit circle corresponding to angle X.
Yes, there are other methods for solving this type of problem, such as using a calculator or graphing the equations to find the intersection point. However, using trigonometric identities and properties is the most common and efficient method for solving equations involving trigonometric functions.
