Answer:

Step-by-step explanation:

107 and y form a straight angle and are supplementary, thus

107 + y = 180 ( subtract 107 from both sides )

y = 73

The sum of the interior angles of a quadrilateral = 360°

Sum the given angles and equate to 360

117 + 79 + 73 + x = 360, that is

269 + x = 360 ( subtract 269 from both sides )

x = 91

Thus x = 91, y = 73 → B

Does anyone know the answer to this one?

polet [3.4K]

Answer:

$\large\boxed{a(x+4)(x-5)=0,\ a\in\mathbb{R}-\{0\}}\\\\\text{for}\ a=1\to\boxed{x^2-x-20=0}$

Step-by-step explanation:

$\text{If}\ x_1\ \text{and}\ x_2\ \text{are the roots of the quadratic equation}\ ax^2+bx+c=0,\\\text{then}\ ax^2+bx+c=a(x-x_1)(x-x_2).\\\\\text{If}\ x_1\ \text{and}\ x_2\ \text{, then they are the roots of the quadratic equation.}\\\\\text{We have}\ x_1=-4\ \text{and}\ x_2=5.\ \text{Therefore we have the equation:}\\\\a(x-(-4))(x-5)=0\\\\a(x+4)(x-5)=0\qquad\text{for any value of}\ a\ \text{except 0}.$
