Let’s denote the angle between angles 1 and 3 through the angle X0.
The sum of the angles is 1 + 3 + X = 180, since they form a developed angle.
Then 56 + 49 + X = 180.
X = 180 – 56 – 49 = 75.
Angle 2 = X = 75 as criss-crossing angles at the intersection of parallel lines m and n secant k.
Answer: Angle 2 is 75.
