The distance between the two buildings is 844.23 feet apart, we go this answer by simply applying the SOH CAH TOA method
<h3>Trigonometry</h3>
Given Data
- Height of Building A (Opp) = 400 feet
- Angle of Elevation θ = 35°
- Distance between the buildings Adj = ??
Applying the SOH CAH TOA Approach we have
Tan θ = Opp/Adj
Substituting our given data we have
Tan 35 = 400/x
0.4738 = 400/x
make x subject of the formula we have
x = 400/0.4738
x = 844.23 feet

Answer:
x = -1
Step-by-step explanation:
add 9.5 to both sides to get x by itself and to keep both sides equal.
x = -1
