Answer:
<3, < 6, <7 are all 102,
<1, <4, <5 and <8 are all 78
Explanation:
If you slide angles 1, 102, 3 qnd 4 down along p, they will fit perfectly over 5,6,7 and 8. So if you find the top four angles, you have found the bottom 4 angles.
<3 is a vertical angle to 102 and vertical angles always have the same measurement.
Angles 1 and 4 are supplemental to 102. That means that the two angles will add to 180. 180 - 102 = 78
