Question

$\triangle xyz \sim \triangle jhi$. what is $m\angle i$?
$m\angle i = \square^\circ$

Explanation:

Step1: Find $\angle Y$ in $\triangle XYZ$

The sum of angles in a triangle is $180^\circ$.
$$m\angle Y = 180^\circ - 29^\circ - 104^\circ = 47^\circ$$

Step2: Match corresponding angles

Similar triangles have congruent corresponding angles. $\angle I$ corresponds to $\angle Y$.
$$m\angle I = m\angle Y$$

Answer:

$47$
