Find by drawing and by calculation the resultant of two vectors 3 and 4 units inclined to each other at
A 30 degree
B 90 degree
C 120 degree
Answered by oobleck
so, can you not draw the vectors? Do you have a protractor?
If not, you can use your knowledge of the values of the trig functions of special angles.

B is easy - just the diagonal of the rectangle, right?
