let BC = x m
DB = x + 7.3m
AB = DB
BC = 10m
let ∠BAC = θ
tanθ = BC/AB
= 10/17.3
= 0.578
θ = 30°
DB = x + 7.3m
AB = DB
BC = 10m
let ∠BAC = θ
tanθ = BC/AB
= 10/17.3
= 0.578
θ = 30°

The angle of elevation of the top of a ladder leaning against a wall m...
Let's call the height of the ladder "h" and the distance from the foot of the ladder to the wall "x".
We can use the tangent function to find the height of the ladder:
tan(angle of elevation) = opposite/adjacent
tan(45 degrees) = h/x
Since the angle of elevation is 45 degrees, and the distance from the foot of the ladder to the wall is given as 7.3 meters, we can substitute these values into the equation:
tan(45 degrees) = h/7.3
Using the fact that tan(45 degrees) = 1, we can simplify the equation to:
1 = h/7.3
To solve for h, we can multiply both sides of the equation by 7.3:
7.3 = h
Therefore, the height of the ladder is 7.3 meters.
