Question

if one angle of a parallelogram is 30° less than twice the smallest angle, then find the measure of each angle​

Answer 1

Answer:

The angles are

70degree

110 degree

70 degree

110 degree

Answer 2

Answer:

Let the smallest angle be x

One angle = 2x - 30°

∴ x + 2x - 30° = 180°

⇒ 3x = 210°

⇒ x = 70°

∴ 2x - 30° = 110°

∴ Angles are 70°, 110° , 70°, 110° .

Step-by-step explanation:

Let the smallest angle be x

One angle = 2x - 30°

∴ x + 2x - 30° = 180°

⇒ 3x = 210°

⇒ x = 70°

∴ 2x - 30° = 110°

∴ Angles are 70°, 110° , 70°, 110° .
