Answer:

The angle of incidence is $\theta_i =42.6^o$

Explanation:

The diagram for this question is shown on the first uploaded image

From the question we are told that

The distance between the mirror and the wall is $a = 33.7 cm$

The height of the above the mirror is $b = 36.7 cm$

Generally the angle which the reflected ray make with the mirror is mathematically evaluated as

$\alpha =tan ^{-1} (\frac{b}{a})$

substituting values

$\alpha = tan ^{-1}( \frac{36.7}{33.7})$

$\alpha =47.4^o$

From the diagram we can deduce that the angle of incidence is

$\theta_i = 90 - \alpha$

So $\theta_i = 90 - 47.4$

$\theta_i =42.6^o$
