A boy 5m tall observes a birdd on top of a pole 20 m high at an angle of elevation 30° calculate the horizontal distance between the boy and the Pole. ​

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

it would be a on edgenuit y

the diagram below is your final answer
