First let's show the work to prove if we are right:
.
So, the answer is A) It has a value greater than 8.
Answer:
A
Step-by-step explanation:
Sum the product of the components in the first row of A with the corresponding components of the first column in B
Repeat this with the components in the second row of A with the corresponding components of the second column in B, that is
AB
=
=
=
= → A
50 + 12m = 460
Subtract 50 from both sides
12m = 410
Divide 12 from both sides to isolate m
m = 34 1/6
Answer:
z is obviously 60 degrees, there are 180 degrees so it has to be 120
Step-by-step explanation:
x = 120
