(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

This example comes straight out of the book. Can someone show intermediate steps?

Book solution: P = 235 N, Tab = 1401N, Tac = 1236NCode (Text):Fx = 0: -0.0933Tab - 0.0846Tac + P = 0

Fy = 0: +0.778Tab + 0.705Tac - 1962N = 0

Fz = 0: +0.622Tab - 0.705Tac = 0

2. Relevant equations

what method did they use

3. The attempt at a solution

determinants & algebraic methods failed.
