Question

A tree 30 ft tall casts a shadow 40 ft long. Find the angle of elevation.

• A. 53${}^o$
• B. 63${}^o$
• C. 73${}^o$
• D. 83${}^o$

Answer 1

The correct option is A 53${}^o$

Here, $h=30x=40$

Let the Angle of Elevation be $A$

So, $\tan A=\frac{30}{40}=\frac{3}{4}\Rightarrow A={53}^o$

Therefore, Answer is ${53}^o$
