Question

find w find value of w. and send fast

Answer 1

z=180-60. [Linear pair]
=120
x+y+z+w=360. (Sum of all exterior angle is 360)
60+100+120+w=360
w=360-280
w=80 degree

Answer 2

First of all the fourth interior angle of the quad is unknown so it's value is

60+80+120+4th angle=360

260+4th angle=360

4th Angle=360-260=100

If u look at the quad where w is marked it is a straight line and straight line angle is 180

So w= 180- 4th angle of quad(interior)

W=180-100=80°
