Use the law of Cosines where
angle A = 14+22=36 degrees
side b = 6 times 7
side c = 6 times 19
So you have a triangle with 2 legs of 42 and 114 with angle A = 36 degrees between them.
The law of Cosines is then
a^2 = 42^2 + 114^2 - 2(42)(114)Cosine(36)
Solve and take the square root.
= 7012.85 taking the square root of it
= 83.74 km apart

x = a - 2by^2
- a
x - a = -2by^2
/-2b
(x - a)/-2b = y^2
square root it:
y = √(x - a)/-2b
(note : everything is inside the square root)

I would like more information please. What line are you referring to?
What the hell it is i cannot understand
Answer:
11x=1
Step-by-step explanation:
15x+4=5+3x+1x Bring everything with an x in front of it to the left side
15x-3x-1x+4=5 Simplify the x values
11x+4=5 Bring the 4 to the right side
11x=5-4
11x=1
