Step-by-step explanation:

Olá!
(2x - 6) + (x+ 10) + (2x + 1) = 180
2x - 6 + x + 10 + 2x + 1 = 180
2x + x + 2x = 180 + 6 - 10 - 1
5x = 175
x = 35
<u>Explanation</u><u>:</u>
From the given figure ,
AB || CD
PQ is a transversal
Given angles are 50° and 130°
50° and x are linear pair
⇛ 50°+x = 180°
⇛ x = 180°-50°
⇛ x = 130°
Therefore, "x" = 130°
and
130° and y are vertically opposite angles which are equal.
⇛ "y" = 130°
Therefore, y = 130°
<u>Additional</u><u> </u><u>comment</u><u>:</u><u>-</u>
- If two parallel lines Intersected by a transversal then
- Corresponding angles are equal.
- Vertically Opposite angles are equal.
- The sum of two adjacent angles is equal to 180° then they are called Linear Pair.
35-18=17
The most side dishes that they could get is 5
5*3=15
15+17=33
