physics

A uniform bar of length 12 m and mass 3 kg is attached to a wall with a hinge that exerts a horizontal force Hx and a vertiscal force Hy on the bar. The bar is held by a cord that makes a 90 degree angle with respect to bar and 43 degrees with respect to wall. What is the magnitude of the horizontal force Hx on the pivot? The acceleration of gravity is 9.8 m/s^2. Answer in units of N.

Thanks!
