Given that P = (-4, -5) and Q = (2,3), express →PQ in the form (k,θ). where k is the magnitude and θ the bearing.
(10 units, 053º)
(9 units, 049º)
(10 units, 037º)
(9 units, 027º)
Correct answer is A
|→PQ| = √[(2-(-4))2 + (3-(-5))2]
|→PQ| = √62+82
|→PQ| = √100
|→PQ| = 10units
tanθ = 3−−52−−4
tanθ = 43
θ = tan−143
= 53º
