Question

of the tree touches the ground making an angle ° with it. The distance between the foot of the tree to the point where the top touches the ground is 8 m. Find ​

Answer 1

Answer:

In right ΔABC,

Using Cosine and tangent angles,

cos 30° = BC/AC

We know that, cos 30° = √3/2

√3/2 = 8/AC

AC = 16/√3 …(1)

Also,

tan 30° = AB/BC

1/√3 = AB/8

AB = 8/√3 ….(2)

From (1) and (2),

Total height of the tree = AB + AC =

16/√3 + 8/√3 = 24/√3 = 8√3 m.
