x=-11
Step-by-step explanation:
Answer:
0
Step-by-step explanation:
the derivative is zero since it has no variable
A and b are perpendicular meaning that they intersect forming 90
b and c are parallel meaning that the intersection of c and a is also perpendicular
11x - 9 = 90 degrees
solve
11x - 9 = 90
add 9 to both sides
11x = 99
divide both sides by 11
x = 9
