You are given two vectors A⃗ =−3.00ι^+7.00j^
and B⃗ =5.00ι^+2.00j^. Let the counterclockwise angles be positive.
What angle θA, where 0∘≤θA360∘, does A⃗ make with the +x-axis?
What angle θB, where 0∘≤θB360∘, does B⃗ make with the +x-axis?
Vector C⃗ is the sum of A⃗ and B⃗ , so C⃗ =A⃗ +B⃗ . What angle θC, where 0∘≤θC360∘, does C⃗ make with the +x-axis?
