Question

A girl observes the top of a tree at an angle of 60° standing 8m away from the tree.

What is the height of the tree​

Answer 1

Answer:

The answer is 13.856.

Step-by-step explanation:

• The tree angle at foot must be 90° because we can't solve the question with only one side and one angle.
• The third angle will be 30° by following the 'sum of angles in ∆' property.
• Use sine rule. Like this:
• $\frac{8}{ \sin(30) } = \frac{x}{ \sin(60) }$
• After using sine rule we get the value of x and that will be 13.856m.

Answer 2

Answer:

The answer is 13.856
