Vector A, expressed in unit vector notation is 58i - 91j +135k and Vector B, expressed in unit vector notation is 61i + 34j - 75k. Find the magnitude and

the coordinate direction angles (a. B. and y) of the sum of the two vectors. \begin{aligned} &\text { Magnitude: } 96 \mathrm{~N} ; \text { a: } 35^{\circ} ; \beta: 68^{\circ} ; \text { y. } 54^{\circ}\\ &\text { Magnitude: } 275 \mathrm{~N} ; \mathrm{c}: 64^{\circ} ; \beta: 102^{\circ} ; \gamma: 77^{\circ}\\ &\text { Magnitude: } 189 \mathrm{~N} ; \alpha: 94^{\circ} ; \beta: 113^{\circ} ; \gamma: 23^{\circ}\\ &\text { Magnitude: } 145 \mathrm{~N} ; \text { cu } 35^{\circ} ; \beta: 113^{\circ} ; \mathrm{\gamma}: 66^{\circ}\\ &\text { Magnitude: } 233 \mathrm{~N} ; \mathrm{cr} 32^{\circ} ; \beta: 78^{\circ} ; \mathrm{y}: 61^{\circ} \end{aligned}
