Answer:
Step-by-step explanation:
Divide both sides by 7:
Subtract 4 from both sides:
4) y = 10x
5) y = 13x
6) 2,1
4,2
6,3
y=0.5x
Correct answer: ∝ = 18.43°
Given coordinates represent one vector in x-y plane, let be v.
v = 3i +1j = xi + yj => x = 3 and y = 1
The angle that this vector builds with the positive direction to the x axis will be found using the tangent.
∝ = tan⁻¹ y/x = tan⁻¹ 1/3 = tan⁻¹ 0.333 = 18.43°
∝ = 18.43°
