Question

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

Answer 1

First

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)
