Question

If A = 3i - 3j then the angle made by vector A with horizontal will be (Counter clock wise):
a) 0°< teta<90°
b) 90° < teta<180°
c) 90° < teta < 270°
d) 270°< teta < 360°​

Answer 1

Answer:

d

Explanation:

this 3i-3j can be rewritten as (3,-3) which represents position.so it belong to 4th quadrant so angle made with horizontal should lie in that quadrant

Answer 2

Explanation:

D is the correct answer
