If one side of a parallelogram is 24° less than twice the smallest angle, then the measure of the largest angle of the parallelogram is
Let the small angle be = x
Then the second angle = 2x - 24°
Since,
Opposite angles are equal the 4 angles will be x, 2x - 24° , x , 2x - 24°
So now by angle sum property:
x + 2x - 24° + x + 2x - 24° = 360°
6x - 48° = 360°
6x = 360° + 48°
6x = 408°
x =
x = 68°
Thus, the smallest angle is 68°
The second angle = 2 (68°) - 24°
= 112°
