<h3>
<u>Explanation</u></h3>
- Given the system of equations.
- Substitute y = -4x in the second equation.
- Substitute the value of x in any given equations. I will substitute the value of x in the first equation.
- Answer Check by substituting both values in two equations.
<u>First</u><u> </u><u>Equation</u>
<u>Second</u><u> </u><u>Equation</u>
Both equations are true for the value of x and value of y.

Polynomial 1 : x²-x²+4x -2+1 = 4x -1
Polynomial 2 : 3x-x-2x²-2+1 = -2x²+2x-1
Polynomial 3 : 4 -2x+x-x²+x²-x² = -x²-x+4
According to the question,
Polynomial 1+Polynomial2+Polynomial3 + Polynomial4 = 6x
=> 4x -1+ (-2x²+2x-1) +(-x²-x+4) + Polynomial4= 6x
=> -3x²-x+2+Polynomial4= 0
<h2>=> 3x²+x -2= Polynomial4</h2>

Answer:
x = 48
Step-by-step explanation:
It is a 90 degree angle. So first you would subtract 42 from 90 degrees. Then you'd get your answer! Hope this helped
