Answer 1

Answer:

Angle x= 60° and exterior angle of x= 120°

Answer 2

Answer:

300

Step-by-step explanation:

First find the interior one

x+30+90=180(angles sum of triangle=180)

or, x= 180-120

or, x=60

Sum of ext. and int. angles =360degree

So, Exterior angle of x= 360-60(total degree - int. angles=ext. angles)

=300degree

So, Ext. angle of x=300 degree
