<span>The value of the determinant of a 2x2 matrix is the product of the top-left and bottom-right terms minus the product of the top-right and bottom-left terms.

The value of the determinant of a 2x2 matrix is the product of the top-left and bottom-right terms minus the product of the top-right and bottom-left terms.

= [ (1)(-3)] - [ (7)(0) ]
= -3 - 0
= -3

Therefore, the determinant is -3.

Hope this helps!</span>

If value of a+b=7and ab=12then find the value of a and b

LiRa [457]

a+b = 7

ab =12

we know that

a and b = ab – a+b

= 12 –7

= 5 ans

For this case we have by definition of trigonometric relations of rectangular triangles that, the sine of an angle is given by the opposite leg to the angle on the hypotenuse of the triangle. Then according to the figure we have:

$Sin (40) = \frac {CA} {7}$

We cleared CA:

$AC = 7 * Sin (40)$

Answer:

Option A
