Question

these angles are... 120° 60° supplementary neither complementary

Explanation:

Step1: Recall angle definitions

Supplementary angles sum to \(180^\circ\), complementary to \(90^\circ\).

Step2: Calculate angle sum

Add \(120^\circ + 60^\circ = 180^\circ\).

Step3: Classify the angles

Since their sum is \(180^\circ\), they are supplementary.
