Alright, lets get started.
We have given an angle made by two road, is 41.4°.
We need to find complementary and supplementary angles of this intersection.
The two angles are called complementary when their addidtion is 90°.
It means for finding the comlpementary angle, we need to subtract the given angle from 90°.
Complementary angle =
°
The two angles are called supplementary when their addidtion is 180°.
It means for finding the supplementary angle, we need to subtract the given angle from 180°.
supplementary angle
°
Hence the complementary angle is 48.6° and supplementary angle is 138.6°. : Answer
Hope it will help :)
