At 10 AM on April 26, 2009, a building 300 feet high casts a shadow 50 feet long. What was the angle of elevation of the Sun?

Short Answer

Expert verified

The angle of elevation of the Sun is80.5376掳.

Step by step solution

01

Given Information

Given that at 10 AM on April 26, 2009, a building 300 feet high casts a shadow 50 feet long.

02

Solution

Suppose the angle of elevation of the Sun is x掳.

We can draw a figure of given problem as:

Now, in 鈻�ABCwe have to find angle B=x掳.

So,

tan(x掳)=ACBCtan(x掳)=30050tan(x掳)=6x掳=tan-1(6)x掳=80.5376掳

So, the angle of elevation of the Sun is80.5376掳.
