Step-by-step explanation:
Given the expression

Determining the factor

so the expression becomes

Factor out the common term 3

Therefore, the required answer as a product with a whole number greater than 1 will be:

Answer:
10
Step-by-step explanation:
it is what it is
Sum of all the interior angles = (5-2)x180 = 540°
540 - 100 - 120 - 100 - 90 = 130°
So the last unknown angle in the polygon is 130°
Sum of all the adjacent angles on a straight line is 180°
Angle 1 = 180 - 130 = 50°
Is there a graph? not sure what to solve.
