Find the measure of all the angles of a parallelogram, if one angle is 24° less than twice the smallest angle.

Given,


Let the smallest angle = x


Than the other angle = (2x – 24)°


So,


x+x+2x – 24 + 2x – 24 = 360


6x = 360 + 48 = 408



Other angles = 2x – 24 = 2×68 – 24 = 136-24 = 112


Angles are = 68, 68, 112, 112
