Answer:
10.39 OR 10.4 m at 46.6° downward or clockwise with +xaxis or 313.4° in anticlockwise direction with + X-axis
Explanation:
D = SQUARE ROOT OF(7.14^2 +(-7.55)^2)
D = 10.39 m
as Dx is positive and Dy IS NEGATIVE hence vector is in 4 th quadrant
tan α= 7.55/7-14
= 1.057
α = 46.6° downward or clockwise with +xaxis
or α =313.4° in anticlockwise direction with + X-axis
