If Mlt1077 Mlt747 And Mlt16139 Find The Missing Measure Of Mlt2 class=

Answer :

Note that a and b are parallel lines with a transversal line of c.

<10 is congruent to <8

so :

<8 = 77

<2 and <8 are supplementary (sum of 180 degrees)

<2 + <8 = 180

<2 + 77 = 180

<2 = 103

The answer is :

<2 = 103 deg
