HELP ASAP 25 points. Vector question
Nutka1998 [239]

Answer:

4v - 7w  = (101 , -36)

6u -8v = (-78 , 58)

2u +v - 4w = (40 , -4)    

11u + 3w = (-88 , 89).

Step-by-step explanation:

u(-5, 7) ; v(6 , -2) ;   w(-11,4)

4v - 7w = (4*6+[-7]*[-11] , 4*[-2] + [-7]*4)

            =(24+77 , -6 - 28)

4v - 7w  = (101 , -36)

6u - 8v = (6*[-5]+[-8]*6 , 6*7+[-8]*[-2] )

            = (-30-48 , 42+16)

6u -8v = (-78 , 58)

2u + v - 4w = (-10+6+44 , 14 -2 -16)

2u +v - 4w = (40 , -4)                  

11u + 3w = (11*[-5]+3*[-11]  ,  7*11 +3*4)

             = (-55-33 , 77+12)

11u + 3w = (-88 , 89)

Answer:

C. 57°

Step-by-step explanation:

All triangles have a sum of 180°.

m∠D + m∠E + m∠F = 180°

35° + m∠E + 88° = 180°

123° + m∠E = 180°

m∠E = 57°
