Mai poured `2.6` liters of water into a partially-filled pitcher. The pitcher now contains `10.4` liters. Mai wants to know how
many liters of water were originally in the pitcher. Three of Mai’s friends drew a diagram (shown) to represent the problem.
You said the solution to your equation `2.6+10.4=` was `13`.
Explain what the solution to the equation means within the context of the problem.

<h2>angle in triangle</h2>
because the triangle above is an isosceles triangle, then both angles are of the same value.
and one thing you should know, the angle above shows the straight angle.
<em>so the sum of all angles is 180</em><em>°</em>
<u>can be written like </u><u>this</u><u> </u><u>:</u>
(5x+13)°+(3x+7)°=180°
5x + 13 + 3x + 7 = 180
8x + 20 = 180
8x = 180 - 20
8x = 160
x = 20
<em>(*the third choice is correct)</em>
