Question

supplementary angles ____________
1 add to 45 degrees
2 add to 270 degrees
3 add to 180 degrees
4 add to 90 degrees

Explanation:

Step1: Recall the definition of supplementary angles

Supplementary angles are two angles whose sum is \(180^{\circ}\).

Step2: Check the given options

Among the options:

• Option 1: \(45^{\circ}\) sum is for complementary - like \(30^{\circ}+15^{\circ}\) (not supplementary).
• Option 2: \(270^{\circ}\) sum is not the definition of supplementary.
• Option 3: \(180^{\circ}\) sum matches the definition of supplementary angles.
• Option 4: \(90^{\circ}\) sum is for complementary angles (e.g., \(30^{\circ}+60^{\circ}\)).

Answer:

1. Add to 180 degrees
