Answer:
<h3>x = 7</h3>
Step-by-step explanation:
The sum of the adjacent side of the trapezium is 180 degrees, Hence;
97 - 3x + 69+5x = 180
166 + 2x = 180
2x = 180 - 166
2x = 14
x = 14/2
x = 7
Hence the value of x is 7
-2 + 8 = 6
because if you have 2 negative circles ●● and 8 positive circles ○○○○○○○○ then once you take away the first two circles you get you answer. You do the opposite. :) ( hope that make sense... )
