a person stands 15 ft from an elephant. determine how tall the elephant is in feet, the given diagram

Answer:
First
Step-by-step explanation:
● tan 30° = opposite/adjacent
Let x be the missing hight
● tan 30° = x/15
Multiply both sides by 15
● tan 30° *15 = (x/15)*15
● tan 30°*15 = x
● x = 8.66 wich is approximatively 5×√(3)
