Give the measure of the supplement of the angle. The measure of the supplement of the angle \( y^{\circ} \) is ( \( \left.\square\right)^{\circ} \). (Type an expression using \( y \) as the variable.)

The measure of the supplement of the angle \( y^{\circ} \) is \( (180 - y)^{\circ} \). This is because supplementary angles are any two angles that add up to \( 180 \) degrees, so you simply subtract the measure of the angle from \( 180 \). Remember, this applies to any angle \( y \) you have! Whether \( y \) is a small acute angle or a larger obtuse one, just plug it into the formula \( 180 - y \), and you’ll find its supplement. Keep practicing—geometry can be both fun and challenging!
