We can see a right triangle in this problem,
where a vertical distance is a leg that opposite to the angle 20⁰ , and horizontal distance is an adjacent leg to the 20⁰ angle.
So,
tan (20⁰) = opposite leg/adjacent leg
tan (20⁰) = vertical distance/horizontal distance
tan (20⁰) = 30 /horizontal distance
horizontal distance= 30/tan(20⁰) ≈ 82.4 in.

Answer: the height of the building is 104 feet
Step-by-step explanation:
The triangle ABC formed is shown in the attached photo. It is a right angle triangle. The height if the building is represented by x feet.
To determine the value of x, we would apply trigonometric ratio.
Tan # = opposite side/adjacent side
From the information given,
# = 60 degrees
Opposite side = x feet
Adjacent side = 60 feet.
Tan 60 = x/60
x = 60tan60 = 60 × 1.7321
x = 103.926
x = 104 feet to the nearest whole number.
