What is ... I am very confused plz help me.

The answer is 40 degrees.

Step-by-step explanation:

Let's look at the bottom triangle first.  We know that the sum of the angles of a triangle is always 180.  We have two 50s, totalling 100, so the remaining angle is 80.

Angle 1 plus the angle we just figured out must also add up to 180, since it's a straight line.   So, angle 1 is 100.

The bottom right angle of the upper triangle is 80, but the same property we used to calculate angle 1.

So, now we have two angles, 60 and 80, with another angle needed to add up to 180.  So, angle 2 is 40.

why can't you?
