The measure of the supplement of an angle is seven times as large as the measure of its complement find the measure of the angle, supplement, and complement.

original angle = 75°

Its supplement 105°

Its complement = 15°

Step-by-step explanation:

We know that,

Let x be the original angle , then its supplement = 180° - x

its complement = 90° - x

As per given,

180° - x = 7(90° - x)

⇒ 180° - x = 630° - 7x

⇒  7x- x = 630° -180°

⇒  6 x = 450°

⇒  x = 75°  [divide both sides by 6]

So, original angle = 75°

Its supplement =  180° - 75° = 105°

Its complement = 90° -75° = 15°

Hence,  original angle = 75°

Its supplement 105°

Its complement = 15°
