Answer:

∠S = 19°

Step-by-step explanation:

Since all angles in a triangle add up to 180°, we must first find how much is left.

<em>180 - 142 = 38</em>

And since we know that the two lines are congruent, we know that the two other angles will be the same. So we divide the remaining by 2

<em>38 ÷ 2 = 19</em>

So both other angles are 19° meaning that ∠S is 19°

Hope this was helpful!
