magnitude and direction of this vector is
-5
1) 5789 uniis:sin
with x-axis
*2) 5189 units:cos-
with X-axis
89
189
-5
3) 45 units:cos-
with X-axis
4) 45 units;sin
with x-axis
9​

Answer 1

Explanation:

magnitude = √ x²+y²

= √( -25)²+40²

= √2225

= 47.18 unit

direction = tan inverse -25/40

= tan inverse (-5/8)

hope this helps you
