Since you were given that angle 1 is 33, then it's simple to find the rest.
1 and 4 are vertical angles, which are always congruent.
This means that angle 4 is also 33.
Angle 2 and angles 3+4 are supplementary. This means that they add up to 180.
If 2 is a right angle, then that means it's 90, making angles 3 and 4 also add up to 90.
We already know 4 is 33, so now we only have to figure out 3.
90 - 33 = 57.
Angle 3 is 57.
Angles 3 and 6 are also vertical angles.
Angle 6 is 57.
Angles 2 and 5 are also vertical angles.
If 2 is 90, then
Angle 5 is 90.
3 = 57
4 = 33
5 = 90
6 = 57
