Answer:
<em>7</em>
Step-by-step explanation:
Sum of angles on a straight line is 180°
12x - 8 + 104 = 180°
12x + 96° = 180°
12x = 180° - 96°
<u>12x</u> = <u>8</u><u>4</u>
12 12
x = <em><u>7</u></em>
11 * 14 = 154 lbs since 11lbs=1 stone 11 stones =154lbs

Use the net:
Rectangle 1: (21 in + 3 in + 21 in + 3 in) by 15 in.
Rectangle 2: 21 in by 3 in
Rectangle 3: 21 in by 3 in
total area = sum of areas of 3 rectangles above.
total area = (48 in * 15 in) + 2(21 in * 3 in)
total area = 720 in^2 + 126 in^2
total area = 801 in^2
