Answer:  Line BC is parallel to line AD. The system of equations has the sum 0 = 14. Since this is a false equation, the system has no solution, which means the lines will never intersect.

I dont know if you wanted the steps but:

x^2-4x-6=0

plug it into the equation:

\frac{-(-4)\sqrt{(-4)^2-4(1)(-6)}}{2(1)}

[tex] \frac{4\sqrt{40}}{2} [/tex]

\frac{4+2\sqrt{10}}{2}    \frac{4-2\sqrt{10}}{2}

x=2+\sqrt{10}

x=2-\sqrt{10}

x^2-4/3x+1/3 x=1 , x= 1/3

2x^2-3x+1=0 x=1 , x=1/2

6x^2+12x=-5

add the 5 to both sides

6x²+12x+5=0 plug the problem into the equation

x=\frac{-12\sqrt{12^{2}-4(6)(5)}}{2(6)}

x=[\frac{-12\sqrt{144-120}}{12}

x=\frac{-12\sqrt{24}}{12}

x=\frac{-12+2\sqrt{6}}{12} x=\frac{-12-2\sqrt{6}}{12}

\frac{-6+2\sqrt{6}}{6} \frac{-6-2\sqrt{6}}{6}

Please help me out with this
Minchanka [31]

Value of x is 140

Tangent are present that means those angles are of 90° and 90° + 90° = 180°

One angle is already given 40°

By angle sum property of Quadrilateral

We can get its value

Answer:

2) 16

Step-by-step explanation:

180 - 124 = 56
