Let's remember some angle pair rules:
-> Co-Interior angles add up to 180º.
-> Alternating angles are equal.
-> Corresponding angles are equal.
-> Vertically opposite angles are equal.
-> Angles on a straight line add up to 180º.
-------------------------------------------------------------------------------------------------------------
Knowing that, and knowing Angle 6 = 102º, you can easily find any of the 7 angles.
I will skip angle 1 for now, you'll understand why.
Angle 2 and Angle 6 are Corresponding, so Angle 2 must be 102º.
Angle 3 is Vertically Opposite to Angle 2, so Angle 3 must be 102º.
Angle 4 is Co-Interior to Angle 6, so we calculate it this way:
Angle 4 must be 78º.
Angle 1 is Vertically Opposite to Angle 4, so it must be 78º.
Angle 5 is Alternating to Angle 4, so Angle 5 must be 78º.
Angle 7 and Angle 5 are On A Straight Line, so Angle 7 is calculated this way:
Angle 7 must be 102º.
Angle 8 is Vertically Opposite to Angle 5, so it must be 78º.

I wrote some parts in bold so you can refer to the rules I wrote above.
-------------------------------------------------------------------------------------------------------------
<u>In summary:</u>
Angles 1, 4, 5, and 8 = 78º
Angles 2, 3, 6 and 7 = 102º
