Question

Please Hurry ASAP:) The magnitude and direction of two vectors are shown in tbe diagram. What is the magnitude of their sum? Will Mark Brainliest and look at the picture to answer.​

Answer 1

Answer:

2√5

Step-by-step explanation:

enclosing angle of 2 vectors: 135°-45° = 90°

sum of two magnitudes= √2²+4²+2*2*4*cos 90°

                                       = √4+16+0

                                       =√20

                                       = 2√5

Answer 2

Answer:  2$\sqrt{5}$

Step-by-step explanation:

$\sqrt{(4 cos45 - 2 cos45)^2 + (4 sin45 +2 sin45)^2}$   =   2$\sqrt{5}$
