Answer:
60°
Step-by-step explanation:
From the attachment,
Opposite side of the triangle= 125 feet
Adjacent=72 feet
Angle of elevation= (θ)
From trigonometry,
Tan (θ)= Opposite side /Adjacent adjacent
Where
(θ)=angle of elevation
If we substitute to above expresion we have
tan(θ)= 125/72
tan(θ)= 1.736
Tan^-1(1.736)=60°
θ= 60°
Hence, the angle of Evel at ion from the fire to the top of the building is 60°
