Answer:
105.8 degree from + X axis
Explanation:
V1 = 46 N at 30 degree
V2 = 63 N at 151 degree
Write the vector form
V1 = 46 (Cos 30 i + Sin 30 j) = 39.84 i + 23 j
V2 = 63 (Cos 151 i + Sin 151 j) = - 55 i + 30.54 j
The resultant of V1 and V2 is given by
V = V1 + V2 = 39.84 i + 23 j - 55 i + 30.54 j = - 15.16 i + 53.54 j
The angle made by resultant of V1 and V2 with X axis is
tan∅ = 53.54 / (- 15.16) = - 3.53
∅ = 105.8 degree from + X axis.
