Let the vector U = {(1,2,4); (0, -1, -3); (2,3,5); (1,0, -2)}. a. Find the dimension and a subspace basis W generated by the vector U.
b. Find the parameter k to u = (2, 3, k^2 + 1) is a the law of W, and deduce [u] w.

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
