the intersection of roads M and N creat a 71.4 degrees what are the complumentry and suplumentry angels of this intersection
A 161.4' ; 18.6'
B 18.6'; 161.4'
C 108.6' ; 18.6'
D 18.6' ; 108.6',
Complementary angles sum up to 90 degrees and supplementary angles sum up to 180 (I remember that because they are alphabetical).
90 - 71.4 = 18.6
180 - 71.4 = 108.6
Therefore, D. is the answer.
