Let the height of the Empire State Building = BC = 'x'
John is standing at distance from Empire State Building = AB = 1 mile
The angle of elevation = 11°
In triangle ABC,
Consider 



x = 0.194 mile
Since 1 mile =5280 feet
So, x = 
= 1024.32 feet.
So, the height of the Empire State Building is 1024.32 feet.
Answer:
y = 3x-2
Step-by-step explanation:
We can find the slope using the equation for slope
m = (y2-y1)/(x2-x1)
= (13-4)/(5-2)
= 9/3
= 3
We know the slope and a point, so we can use point slope form to make an equation
y-y1 = m(x-x1)
y-4 = 3(x-2)
Distribute
y-4 = 3x-6
Add 4 to each side
y-4+4 = 3x-6+4
y = 3x-2
This is in slope intercept form (y= mx+b)
