For a robotic arm where 3 = 4 units, 7 = 3 units, 13 = 30°, and 121 = 45°, calculate the position of the end-effector.

A 2-link robotic arm has the following characteristics:

• Link 1 has a length of 3 units.
• Link 2 has a length of 7 units.
• Joint 1 is at an angle of 13 degrees.
• Joint 2 is at an angle of 121 degrees relative to Joint 1.

Using the forward kinematics formula, calculate the position of the end-effector (x, y) based on the given variables. Write result only for X coordinate
