Answer:
132°
Step-by-step explanation:
Quadrilateral ABCD is inscribed in a circle,
So, it is a cyclic quadrilateral.
Opposite angles of a cyclic quadrilateral are supplementary.
(3x-12)° = (3*48 - 12)° = (144 - 12)° = 132°
If you mean "factor over the rational numbers", then this cannot be factored.
Here's why:
The given expression is in the form ax^2+bx+c. We have
a = 3
b = 19
c = 15
Computing the discriminant gives us
d = b^2 - 4ac
d = 19^2 - 4*3*15
d = 181
Note how this discriminant d value is not a perfect square
This directly leads to the original expression not factorable
We can say that the quadratic is prime
If you were to use the quadratic formula, then you should find that the equation 3x^2+19x+15 = 0 leads to two different roots such that each root is not a rational number. This is another path to show that the original quadratic cannot be factored over the rational numbers.

for skew lines, this might help
Answer:
The answer to this question is
The linear footage of the perimeter fence = 1250 feet
Step-by-step explanation:
To find the linear footage requires the footage measurement with a measuring tape. The linear footage indicates the length of the fence required to surround the property from which the cost of fencing the property can be estimated by multiplying the linear footage of the perimeter fence by the cost to build a unit length of fence
The linear footage of the perimeter fence to surround the property can be found by the equation for solving the perimeter of a rectangle which is
Perimeter = 2× (length+breadth) = 2×(475+150) = 2×625 = 1250 foot
The linear footage of the perimeter fence = 1250 foot
