Q. Which pair of angles are supplementary?A)69∘ and 133∘B)106∘ and 74∘C)44∘ and 129∘D)97∘ and 93∘E)None of these are correct.
Define Supplementary Angles: Define what supplementary angles are. Supplementary angles are two angles whose measures add up to 180∘. We will check each pair of angles to see if their sum equals 180∘.
Check First Pair: Add the measures of the first pair of angles (69° and 133°) to see if they are supplementary.69°+133°=202°Since the sum is not equal to 180°, this pair is not supplementary.
Check Second Pair: Add the measures of the second pair of angles (106∘ and 74∘) to see if they are supplementary.106∘+74∘=180∘Since the sum is equal to 180∘, this pair is supplementary.
Check Third Pair: There is no need to check the remaining pairs since we have already found a pair that is supplementary. However, for completeness, we will check the third pair (44∘ and 129∘).44∘+129∘=173∘Since the sum is not equal to 180∘, this pair is not supplementary.
Check Fourth Pair: Check the fourth pair (97∘ and 93∘) to confirm if they are supplementary or not.97∘+93∘=190∘Since the sum is not equal to 180∘, this pair is not supplementary.
