Question

plz answer it.as fast as possible

Answer 1

sum of outer angles on polygon =360

360=45+90+105+x

360-240=x

x=120

interior angles of a regular polygon

{180(#of angles-2)}/#of angles

{180(5-2)}/5

{180*3}/5

540/5

108=x

exterior angles = 360

2x+2x-5+3x-10+x+15=360

8x=360

x=80

Answer 2

hlo mate.

here is your answer.
___________________
*we know,
the measure of an exterior angle =360.
=90 +45+105 +x=360 degree.
=280+x=360 degree.
x=360-280
=60 degree.

*the interior angles of an regular pentagon is 540 degree.
5x=540.
x=540÷5.
x=18.
