Answer:
Option A is the correct answer.
Step-by-step explanation:
The sum of interior angles of a polygon is given by (n-2) x 180°, where n is the number of sides.
The sum of interior angles will not affect irregularity of polygon, it is same for regular and irregular polygon.
For a pentagon n =5.
Sum of interior angles = (5-2) x 180 = 3 x 180 = 540°
Option A is the correct answer.

Answer:
(7y + 3x)(7y - 3x)
Step-by-step explanation:
a² - b² = (a + b)(a - b)
49y² - 9x² = (7y)² - (3x)² {a = 7y ; b - 3x}
= (7y + 3x)(7y - 3x)

3x-4y=12
4y=3x-12
y=(3x-12)/4
y=(3/4)x-3
