Question

how to solve this problem guys by explaining​

Answer 1

Answer:

z = 90

y = 120

x = 150

x + y + z = 360

Step-by-step explanation:

Long method,

y = 90 + 30 = 120 (sum of two interior angles is equal to the exterior angle of the opposite angle)

z = 180 - 90 = 90 (Supplementary angles )

x = 180 - 30 = 150(Supplementary angles)

x + y + z = 90 + 120 + 150 = 360

Short method,

Sum of exterior angles of any figure is always equal to 360.

Answer 2

Answer:

then

x=150°

y=120°

z=90°

so x+y+z= 150+120+90= 360°
