7. Find the measure of the angle of elevation of the sun when a boy 5 feet tall cast's a shadow

Alecsey [184]

Answer:

$45\degree$

Step-by-step explanation:

We use trigonometry to find the angle of elevation.

From the diagram, the angle of elevation of the sun is $\angle A$

Recall the mnemonics SOH CAH TOA.

$\tan A=\frac{Opposite}{Adjacent}$

$\tan A=\frac{5}{5}$

$\tan A=1$

$A=\tan^-1{1}=45\degree$

Therefore the angle of elevation of the sun is $45\degree$
