Lines ℓ and m are intersected by transversal t and ℓ ∥ m. There are two vertical parallel lines l and m intersected by another line t making angles 1 and 3 with l and 5, 7 with m. 1 ,4 and 2 , 3 are opposite angles at the point of intersection of l and t. 5, 8 and 6, 7 are opposite angles at the point of intersection of m and t. If m∠3 = 126°, what is m∠5?
