-3 (-4 + -x ) = (-4(x) × 2 ) + 6
-3 (-4-x) = (-4x × 2) + 6
-12 + 3x = -8x + 6
3x - 12 = 6 - 8x
add 8x on both sides
11x - 12 = 6
add 12 on both sides
11x = 18
<em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>1</u></em><em><u>1</u></em><em><u>/</u></em><em><u>1</u></em><em><u>8</u></em>
A- 10.5

Answer:
142 degrees
Step-by-step explanation:
Easy, 180 degrees in a triangle... so 180-73-69 is 38... now two angles combined on a staight line is also 180 degrees. So now 180 degrees minus 38 is 142 degrees.
