Answer:
105°. Select Alternate Interior Angles Theorem.
Step-by-step explanation:
In my country, we call them alternate angles. It's basically just another term in some countries for "Alternate Interior Angles Theorem".
Since p and q are parallel and t cuts through both of them, 3 and 5 are equal while 4 and 6 are equal. Thus, if m ∠3 = 105°, then m∠5 would also be 105°
