" 11.If "|vec a+vec b|=60,|vec a-vec b|=40" and "|vec b|=46," find "|vec a|

If |vec(a)+vec(b)|=60,|vec(a)-vec(b)|=40 and |vec(b)|=46 find |vec(a)| .

|vec a+vec b|=60,|vec a-vec b|=40|vec b|=46f in d|vec a|

If | vec a+ vec b|=60 ,\ | vec a- vec b|=40\ | vec b|=46 , \ Then find | vec a|

If |vec(a)+vec(b)|=60, |vec(a)-vec(b)|=40 and |vec(b)|=46 , then |vec(a)| is .............. .

find | vec a |, | vec b | if (vec a + vec b) * (vec a-vec b) = 8 and | vec a | = 8 | vec b |

Find |vec a| and |vec b| if (vec a + vec b).(vec a - vec b) = 3 and 2|vec b| = |vec a| .

Let vec a,vec b, and vec c are vectors such that |vec a|=3,|vec b|=4 and |vec c|=5, and (vec a+vec b) is perpendicular to vec c,(vec b+vec c) is perpendicular to vec a and (vec c+vec a) is perpendicular to vec b. Then find the value of |vec a+vec b+vec c|

If two vectors vec a and vec b such that |vec a|=2, |vec b|= 3 and vec a.vec b = 4 , find |vec a - vec b|

Find |vec a| and |vec b|, if :(vec a+vec b)vec a-vec b=8 and |vec a|=8|vec b|

vec a+vec b+vec c=vec 0,vec |a|=3,|vec b|=5 and |vec c|=7 find the anglebetweeen vec a and vec b
