triangle is at an angle of
1) 30° with the first vector
2) 150 with the first vector
3) 100° with the first vector
4) 150° with the first vector

Answer 1

Answer:

2 is the answer of your question

Answer 2

ANSWER:



The resultant of three vectors 1,2, and 3 units whose directions are those of the sides of an equilateral triangle is at an angle of. Hence, angle with first vector is 180-θ=150∘.
