If one angle of a parallelogram is 24° less than twice the smallest angle then the largest angle of the parallelogram is?

If one angle of a parallelogram is 24° less than twice the smallest angle then the largest angle of the parallelogram is?

Explanation

Let smallest angle = x

Then largest angle = 2 x − 24°

But x + 2 x − 24° = 180°

⇒3 x − 24° = 180°

⇒3 x = 180° + 24 = 204°

⇒x = 204/3 = 68°

∴ largest angle = 180 − 68° = 112°
