Use the quadratic formula to get x = (3 - 2*sqrt(6))/3 or x = (3 + 2*sqrt(6))/3
Answer:
The slop of line perpendicular to line y = 
x - 2 is ( - 3)
Step-by-step explanation:
Given Line equation as ,
y = x - 2
The equation of line is y = mx + c
Slop of this line (m1) =
Now second line with slop (m2) is perpendicular to line first , then
(m1) × (m2) = - 1
So, (m2) =
Or , (m2) = 
∴ (m2) = - 3
Hence the slop of line perpendicular to line y = x - 2 is ( - 3) Answer
The picture is difficult to read, but it looks like
∠ADB = 2x²
∠ACB = 10x
These two angles have equal measure, so you have
2x² = 10x
2x(x -5) = 0 . . . . . subtract 10x and factor
x = 0, or x = 5
The measure of arc AB is twice the measure of either inscribed angle, so would be
arc AB = 2×10x
= 2×10×5
= 100 . . . . . degrees
Arc AB is 100°.
