The measurement of an angle is five times the measurement of its supplement.What is the measurement of the angle? Is it 30°, 35°, 40°, or 45°?
Two angles that are supplements add up to 180°. "The angle" is five times its supplement. If I call the supplement 'S', then 'the angle' = 5S . S + 5S = 180° Combine like terms: 6S = 180° Divide each side by 6 : S = 30° The supplement of 'the angle' = 30°. That's one of the choices. "The angle" = 5S = 150°. That's NOT one of the choices.
