प्रश्न
The measure of an angle is twice the measure of its supplementary ang Find its measure.
उत्तर
Given that
The angle measure of an angle is twice of the measure of the supplementary angle.
Let the angle measured will be ‘x’ say
∴The supplementary angle of x is 180 - x as per question
x° = 2 (180 - x)°
x° = 2 (180°) - 2x°
⇒ 3x° = 360°
⇒ x° = 120°
∴ The angle measured is 120°.
