The measure of an angle is 45∘. The measures of its complement and supplement are respectively ___.
135∘, 45∘
150∘, 50∘
45∘, 135∘
35∘, 145∘
An angle + it's complement =90∘
⇒45∘+x∘=90∘
⇒x∘=45∘
Angle + it's supplement =180∘
⇒45∘+y∘=180∘
⇒y∘=180∘−45∘
⇒y∘=135∘
In the given figure two parallel lines l,m are intersected by a tranversal. If ∠4=45∘ then ∠3 and ∠6 are
