The answer is: " 54 ° " .
____________________________
→ The m∠2 {"measure of angle 2"} in the figure shown is: " 54 ° " .
____________________________
Explanation:
____________________________
In the figure shown in the "image attached" :
∠1 and ∠2 are "consecutive exterior angles" ;
and: "consecutive exterior angles" are "supplementary" ;
→ which means that their measurements add up to " 180° " .
____________________________
So: Given: " m∠1 = 126 " ;
We are asked to find: " m∠2 " .
→ {the measure of "angle 2" }.
____________________________
To solve:
____________________________
→ " m∠2" = 180 − ( m∠1 ) ;
= 180 − ( 126 ) ;
= 54 .
____________________________
The answer is: " 54 ° " .
____________________________
The m∠2 {"measure of angle 2"} in the figure shown is: " 54 ° " .
