Answer:

63°

Step-by-step explanation:

From the diagram, the angle of elevation from the child to the top of the tree can be calculated using the tangent ratio.

Recall SOH-CAH-TOA from your Trigonometry class.

The tangent is opposite over adjacent.

$\tan(A) = \frac{14}{7}$

$A = \tan^{ - 1} ( 2)$

$A = 63.43 \degree$

The angle of elevation is 63° to the nearest degree.

450/4 = 112.5
