Answer:
The difference in area between the trapezoid and the rectangle is 10 in²
Step-by-step explanation:
The dimensions of the trapezoid are given as follows;
Base 1, a = 12 in
Base 2, b = 10 in
Height, h = 10 in
Area, A of trapezoid;

The dimensions of the rectangle are given as follows;
Base = 12 in
Height = 10 in
Area, A of rectangle;
Base × Height = 12 × 10 = 120 in^2
Therefore, the difference in area between the two packages is found as follows;
Difference in area between trapezoid and rectangle = 120 - 110 = 10 in²
The difference in area between the trapezoid and the rectangle = 10 in².

True
Explanation:
3 feet is 1 yard so 13/3 is 4.3 yards approximately
Answer:
C
Step-by-step explanation:
the sum of the exterior angles of a polygon = 360°
the exterior angle to 93° = 180° - 93° = 87°
summing the exterior angles and equating to 360
x + 52 + 87 + x + 3 + 78 = 360 , that is
2x + 220 = 360 ( subtract 220 from both sides )
2x = 140 ( divide both sides by 2 )
x = 70
