Answer:
r = 5.696 and θ = 157.17°.
Step-by-step explanation:
the point is (-5.25,-2.21). The distance from the point to the origin is calculated with the formula
r = 5.696 m.
I drew the point and the distances in the plane. to find te angle we can use the sin formula:
sin(θ) =
θ = .
within the range of -180° and 180° the angle will be θ = 180-22.83 = -157.17°
