Please help test on angles and triangles

angle 2=78 degrees

angle 4=78 degrees

Step-by-step explanation:

so  angle 2 is equal to angle 8 bc they are alternate interior angle. we know that angle 8 is 78 degrees bc 180-102=78.

angle 4 is equal to angle 6 bc they are alternate exterior angles. angle 6 is also 78 degrees.

also 2 and 4 are vertical angles which is why they are congruent
