Find (a) u + v, (b) 2v, (c) u -v, (d) 3u - 2v when u (1, 2, 3), v (0, 1,1) 2. solve for x, where u (1,-1, 2), w: (0, 2, 3), and w # (0, 1, 1). 3x + 2u-v + 2w-0 ans 3. write v as a linear combination of u, u2, and u, if possible. v- (4, 4, 5), , 2, 3) ans:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
