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
