Required
Determine the possible measure of square from the rectangular sheet
To do this, we simply calculate the greatest common factor (GCF) of the dimension of the rectangle.


The common factor is: 5
<em>Hence, the side length of the square is 5cm</em>
Answer:
Step-by-step explanation:
-7x + 12 + (-8x + 48) = 180
-15x + 60 = 180
-15x = 120
x = -8
m<BDC= -7(-8)+ 12 = 56 + 12 = 68
m<CBA = -8(-8)+48 = 64+48 = 112
