LET THE ANGLES OF THAT QUADRILATERAL BE 2x,4x,7x and 5x.
= Sum of angles of a quadrilateral = 360°
= 2x + 4x + 7x + 5x = 360°
= 18x = 360°
= x = 360° ÷ 18
= x = 20°
therefore, first angle = 2x = 2 × 20 = 40
second angle = 4x = 4×20=80
third angle = 7x = 7×20 = 140
and fourth angle = 5x = 5×20 = 100
