Answer:
S2 = (S1+S3)/2
Step-by-step explanation:
The area of a trapezoid is the product of the midline length and the height. The parallel lines have divided the height into three equal pieces, so the midline of the middle piece will be the average of the midline lengths of the top and bottom pieces.
The result is that the area of the middle part is the average of the areas of the top and bottom parts:
S2 = (S1+S3)/2
No because 6 is not a factor of 16
Answer:
106 and 107
Step-by-step explanation:
Integers are just numbers that doesn't have a decimal point.
1, 2, 3, 4, and 5 are integers.
1.123, 2.45312, 3.5, 7.9 are NOT integers
105 is between 106 and 107.
So if i assume your trying to get 180 Degrees then that means 180-57 degrees = angle 8 which would be 123 degrees.
