Three forces act on a particle: F1=10i^+0j^+0k^\mathbf{F}_1 = 10\hat{i} + 0\hat{j} + 0\hat{k} N, F2=0i^+10j^+0k^\mathbf{F}_2 = 0\hat{i} + 10\hat{j} + 0\hat{k} N, and F3=0i^+0j^+10k^\mathbf{F}_3 = 0\hat{i} + 0\hat{j} + 10\hat{k} N.
What is the unit vector in the direction of the resultant R=F1+F2+F3\mathbf{R} = \mathbf{F}_1 + \mathbf{F}_2 + \mathbf{F}_3, and which direction angle (rounded to one decimal place) does R make with the negative z-axis?
