A line makes angles of 45^ and 60^ with the positive axes of X and Y respectively. The angle made by the same line with the positive axis of Z , is

Options

  1. A30^ or 60^
  2. B60^ or 90^
  3. C90^ or 120^
  4. D60^ or 120^

Correct answer

D. 60^ or 120^

Step-by-step solution

Given =45^ , =60^ , =? array l ² + ² + ² =1 ² =1- 1 2 - 1 4 = 1 4 y =60^ or 120^ array
