Find a unit vector that is orthogonal to both i + j and i + k.

i - j - k

Step-by-step explanation:

Taking the cross product between two vectors will give you a third vector that is orthogonal(perpendicular) to both vectors.

<1,1,0> x <1,0,1>

the determinate of the matrix: <1,-(1),-1>

or: i - j - k

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

tried on you are knowing that we can't leave the picture in the graph ok no problem now you need to send it in the question group
