Question

the question is below :)

Answer 1

It is given that AB is a straight line,

= The total angle is 180°

So,

42 + x + 29 = 180

71 + x = 180

x = 180 - 71

x = 109°

Answer 2

Step-by-step explanation:

AB is a straight line.

So, 42° + x° + 29° = 180°

==> 71° + x° = 180°

==> x° = 180° - 71° = 109°.

Therefore, the angle x measures 109°.
