Answer 2

Answer:

x + y + z + w = 360°

Step-by-step explanation:

First, we calculate the values of each :

(Example) z + 60° = 180° [Linear Pair]

= z = 180 - 60 = 120°

Using the same method to calculate the rest of the values -

Y = 100°

x = 60°

Now, the fourth angle of the quadrilateral = (360 - Sum of all angles)

= 360 - (60 + 80 + 120) = 360 - 260 = 100

Therefore, w = 80°
