Answer:

? is 59 degrees

Explanation:

the two angles created by the intersecting lines are vertical angles and are equal

also, we know there are a total of 180 degrees in a triangle, so

180 - (21 + 49) = 100

this will help us find '?' because we can add 21 and 100, to get 121, then deduct 121 from 180 to get the value of ? which is 59
