There are three cables holding a beam in place. one cable, AC, is horizontal and coming off the left top of the beam. it has a value of 4KN. Another cable,AD, makes a 30 deg angle with AC and has a value of 5.2 KN. I need to find the magnitude of the third cable,AE, and the total force on the beam,AB. The beam makes a 65 deg angle, and AE makes a 50 deg angle. The beam and AE make a triangle, and AC and AD make a triangle.(adsbygoogle = window.adsbygoogle || []).push({});

I can find the total value of the addition of AC and AD, which is 8.9 KN. but i cant figure out any way to find the value of AE. If i can get AE, AB will be easy to find.

I made a rough pic with paint, but its too big to attach.

this is in the component force section of the book.
