Kitten · Answer 1

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.
