Question Analysis

This question involves the concept of supplementary angles.

Key Concept Explanation

Supplementary angles are two angles whose measures add up to 180°. This is a fundamental concept in geometry used to describe relationships between angles.

Step-by-Step Solution

1. Analyze each option:

A.For the pair 79° and 21°: Calculate 79° + 21° = 100° ≠ 180°.

B.For the pair 38° and 62°: Calculate 38°+ 62° = 100° ≠ 180°.

C.For the pair 147° and 133°: Calculate 147° + 133° = 280° ≠ 180°.

D.For the pair 35° and 155°: Calculate 25°+ 155° = 180°.
