No idea where angle 4 is, but you need to recall that
vertical angles are congruent
alternate int/exterior angles are congruent
adjacent angles are supplementary
etc.
Time to review your theorems on parallel lines and their transversals
lines m and n are parallel. If m∠2 = 150°, find the measure of the following angles
