The height of the tree as per sine of an angle in a right-angle triangle is 12.5 meters.
Sine of an angle in a right-angle triangle is the ratio of the height to the hypotenuse of that triangle.
Here, the tree and it's shadow forms a right-angle triangle along with the base.
Let, the height of the triangle is x.
The length of the height of the hypotenuse is 25 meters.
The angle of elevation from the ground to the top of the tree is 30°.
Therefore, sin (30)° = (x / 25)
⇒ 0.5 = (x / 25)
⇒ x = 0.5 × 25
⇒ x = 12.5
Therefore, the height of the tree is 12.5 meters.
