Find an angle who supplement is three times it's complement. Can you also give it in an equation form?

45°

Step-by-step explanation:

let the angle be x, then

The supplement of x is 180 - x and the complement of x is 90 - x, thus

180 - x = 3 (90 - x) ← equation of model, that is

180 - x = 270 - 3x (add 3x to both sides)

2x + 180 = 270 (subtract 180 from both sides)

2x = 90 (divide both sides by 2)

x = 45

Thus required angle is 45°
