Answer: The angle equals 45 ∘ and the supplement is 135 ∘
Explanation:
Since the supplement is three times the angle, we can say s = 3 a
Since we know the supplement is
180 − a , we can plug that in.
180 - a = 3a
180 = 4 a (add a to both sides)
45 = a (divide both sides by 4)
Since we know the angle now, all we have to do is multiply it times 3 to find the supplement.
45 × 3 = 135
