Um, We know that the total interior angle in this parallelogram is 360° because there is the formula that help you with it: 180°(n-2) where n represent the total side of the figure, so 180°(4-2) =180°(2) =360° Next, We see that angle L and angle N are equal with each other, and so angle O and M. Now, we have this equation: (x+40°)+(x+40)°+(3x)°+(3x)°=360° x°+40°+x°+40°+3x°+3x°=360° 8x°+80°=360° Subtract 80° for both side 8x°+80°-80°=360°-80° 8x°=280° x=35° Angle O: 3x° =3(35)° =105°. As a result, angle O is 105°. Hope it help!
