Answer:
option D
(2.6 , 3.1 )
Explanation:
First quadrant is where x and y values are positive.
Given in the question,
magnitude of vector = 4
angle at which vector is incline from x-axis = 50°
Vertical component (y component)
sinΔ = opp / hypo
sin(50) = vertical / 4
vertical = sin(50)(4)
= 3.06
≈ 3.1
Horizontal component (x component)
cosΔ = adj / hypo
cos(50) = horizontal / 4
horizontal = cos(50)(4)
= 2.57
≈ 2.6
