'12' and '48' (choices 'A' and 'D') will both work as common denominators.
The least one is '12' .
Since 4 is a factor of 12, any multiple of 12 is also a multiple of 4 , and can
serve as a common denominator. The smallest multiple of 12 is 12 itself.
14 is a multiple of 7 and 14
Answer:

Step-by-step explanation:
To express the given product (108 X 125) as a product of prime factors
Step 1: Express each of the numbers as a product of its prime factors.

Step 2: Write the product together, and combine any like terms if any
Therefore,

8+4x-12+3x<=24
-4+7x<=24
7x<=28
X<=4
The given convex polygon has 7 sides
Hence its sum of interior angles is given by the formula , (number of sides-2)x180°
=> (7-2) x 180°
=> 5 x 180°
=> 900°
The sum of all angles must be equal to 900°
The given six angles are :
139°,126°,106°,129°,141°,112° , x°
=> 139+126+106+129+141+112+x = 900°
=> 753 + x = 900
=> x = 900-753
=> x = 147°
Hence 147° is the required answer.
