Question

A boy 0.5m tall is standing at a distance and watching a balloon tied to a pole of 20 m long at an angle of 30 as he walks towards it the angle changes to 60. Find the distance he walked towards the pole

Answer 1

Step-by-step explanation:

this is the way you would get the distance walked by the

Answer 2

Answer:

distance of the pole =20m.

for 30° angle

tan30°=1/√3

therefore distance between the pole and the boy=20√3m.

again,

for 60°angle,

tan60°=√3/1

therefore, distance from the boy to the pole = 20/√3

now, the distance he walked towards the pole = 20√3-20/√3

= 60-20/√3

= 40/√3

= 40×√3/√3×√3

=40√3/3m . answer
