Seagull is 27 ft high
Step-by-step explanation:
Given in the question,
length of bridge = 54ft
angle of elevation = 30°
It is a right angle triangle question and we will use trigonometry identity to the solve the question.
sinФ = opposite / hypotenuse
sin(30) = height / 54
height = 54(sin(30)
height = 27 ft
So, seagull is 27 ft high above the ground.
