 The measure of angle 1 is 142°

Step-by-step explanation:  ∠6 = 38°

∠6 and ∠1 are supplementary, so the total m∠6 + m∠1 = 180°

180° - 38° = 142°

BTW Angles 1, 3, 5 & 7 are all 142° Also, supplementary angles include 2&3, 3&4, 4&5, 2&5, 6&7

last one.

step-by-step explanation:

last one.

generally speaking, the others follow some sort of pattern that correlates to either linear (looks like a straight line) or sinusoidal (looks like an s).

the last one is just a random cloud of points that doesn't correlate to any particular known order.
