Answer:
Either, (9+√69)/6 or (9-√69)/6
Step wise:
3x²-9x+1=0-------------------(i)
comparing equation onw with (ax²+bx+c=0), we get,
a=3, b=-9, c=1
now,
using Quadratic Formula,
(-b±√b²-4ac)/2a=x
{-(-9)±√(-9)²-4.3.1}/2.3=x
(9±√81-12)/6=x
(9±√69)/6=x
Taking +(ve) sign Taking -(ve) sign
(9+√69)/6=0 (9-√69)/6=0
∴(9+√69)/6=0 ∴(9-√69)/6=0
[∵They cannot be further solved]
Answer:

Step-by-step explanation:
The three angles need to add up to 180 degrees!
Answer:
x < 3
Step-by-step explanation:
2(4+2x)>5x+5
Distribute
8 +4x > 5x+5
Subtract 4x from each side
8 +4x-4x > 5x-4x+5
8 > x+5
Subtract 5 from each side
8-5 > x+5-5
3 > x
X must be less than 3
