So you make them the same common denominator
As you see, 2/10 = 8/40
2/4 = x/40, multiply by 10
2/4 = 20/40
Then add because same denominator
Now you would get:
8/40 + 20/40 = 28/40
False. When a quadrilateral has two sets of parallel sides ,like I drew below, all four corners form right angles.

Angles are equal because of the vertical angle thm
2x + 15 = 145
2x = 130
x = 65
