Step-by-step explanation:
adjacent angles of a parallelogram is 180°
=> (5x - 5) + (10x + 35) = 180°
=> 5x - 5 + 10x + 35 = 180
=> 15x + 30 = 180
=> 15x = 180 - 30
=> 15x = 150
=> x = 10
therefore adjacent angles are
=> 5x - 5 => 5×10 - 5 => 45°
and
=> 10x + 35 => 10×10 + 35 => 135°
their ratio is 45° : 135° => 1 : 3
