We have one angle that is 92°.
92° and 3 are supplementary angles (they add up to 180°)
So:
92+ angle 3 = 180
angle 3 = 180-92
Angle 3 = 88°
Now, we have that 2 is opposite to 92°, that means that they are congruent angles (equal )
Angle 2 =92°
Also angle 3 and 1 are congruent:
angle 1= 88°
The same angle repeat across the line t:
4=88°
5=92°
6=92°
7=88°
