Answer:

let's consider the figure I edited and named angles as 1 2 and 3 respectively

so angle 1 = angle 2( vertically opposite)

therefore;


14x - 77 = 9x - 27 \\ 14x - 9x = - 27 + 77 \\ 5x = 50 \\ x = 10(divide \: by \: 5)

now

angle 2= 9(10)-27

=90-27

=63°

next is angle 3

i.e angle z

bye linear pair axiom


z + 63 = 180 \\ z = 180 - 63 \\ z = 117

answer is x=10° and z=117°
