recall d = rt, distance = rate * time.
let's say airplane A is going at a rate of "r", therefore airplane B is moving faster, at a rate of "r + 80".
now, after 3 hours, both planes have been travelling for 3 hours each, and say if A has covered "d" miles, then B has covered the slack of 2490 - d.

Answer:
29
Step-by-step explanation:
In parallel lines, allied angles have a sum of 180.
Therefore, angle CBD + angle EAB = 180
Therefore, 42 + 109 + x = 180
x + 151 = 180
x = 29
