Answer:

d = 14

Step-by-step explanation:

$\sin \: 45 \degree = \frac{a}{7 \sqrt{2} } \\ \\a = 7 \sqrt{2} \sin \: 45 \degree \\ \\ a = 7\sqrt{2} \times \frac{1}{ \sqrt{2} } \\ \\ a = 7 \\ \\ \sin \: 30 \degree = \frac{a}{d} \\ \\ \frac{1}{2} = \frac{7}{d} \\ \\ d = 2 \times 7 \\ \\ d = 14$

A system of linear equations with more equations than unknowns is sometimes called an overdetermined system. Can such a system b

shepuryov [24]

Answer:

A. Yes, overdetermined systems can be consistent.

As, the system of equations below is consistent because it has a solution

$x_{1}=2$ , $x_{2}=4$ , $x_{1}+x_{2}=6$ .

Step-by-step explanation:

We have,

'Over-determined system is a system of linear equations, in which there are more equations than unknowns'.

For e.g. Let us consider the system,

2x - 3y = 1

3x - 2y = 4

x - y = 1

Plotting these equations, we see from the graph below that,

The only intersection point is (2,1). Thus, x= 2 and y= 1 is the solution of this system.

Thus, over-determined system can be consistent.

According to the options,

Option C is not correct as,

$x_{1}=2$ , $x_{2}=4$ implies $x_{1}+x_{2}=2+4=6\neq 8$ .

Hence, option A is correct.
