Answer:
The height of the tree is 20.62ft
Step-by-step explanation:
Hello,
To solve this problem, we need to a good pictorial understanding of the situation.
See attached document for better illustration.
Next we find the value of x and then add the height of john to it.
To find x, we nee to use trigonometric ratio
SOHCAHTOA
Tanθ = opposite/ adjacent
θ = 38°
Adjacent = 20ft
Opposite = x
Tan38 = x / 20
x = 20tan38
x = 20 × 0.7812
x = 15.62ft
The height of the tree = x + John's height
Height of the tree = 15.62ft + 5ft
Height of the tree = 20.62ft
