Answer:
∠RST, ∠TSR, ∠S
Step-by-step explanation:
When using three letters, the middle letter must be the vertice of the angle, and the other two are the points surrounding it. You can also just use a single letter to name the angle if there is only one angle at that vertice.

12 divided by 2 = 6
<em>Answer:</em>
<em>y = 49°</em>
<em />
<em>Step-by-step explanation:</em>
<em>∠DBC = ∠CBD { BC = DC ; angles oppostie to the equal sides are equal}</em>
<em />
<em>∠DBC + ∠CBD + ∠C = 180 {angle sum property of triangle}</em>
<em />
<em> y + y +82 = 180</em>
<em />
<em> 2y = 180 - 82</em>
<em />
<em> y = 98/2 = 49</em>
