angle A = 30
(2x-9) = (2x+21)
+9 +9
2x=2x+30
-2x -2x
=30

Step-by-step explanation:
Answer:
- D = -87
- Dx = 174
- Dy = -435
- Dz = 0
- (x, y, z) = (-2, 5, 0)
Step-by-step explanation:
The determinant of the coefficient matrix is ...

The other determinants are found in similar fashion after substituting the constants on the right for each of the above matrix columns, in turn.
Those determinants are ...



The solutions are ...
x = 174/-87 = -2
y = -435/-87 = 5
z = 0
That is, (x, y, z) = (-2, 5, 0).
To make the second gear aligned with the first it would have to rotate 5 times, a total of 120 seconds and/or 2 minutes will pass
So the answer is I.
