Question

fine the value of x+y+z​

Answer 1

x = 180°- 90° = 90°

so, x = 90°

y = 120°

z = 180° - 30° = 150°

so, z = 150°

According to question,

x+y+z = 90° + 120° + 150° = 360°

Hope it helps you......☺️

Answer 2

Answer:

x +y +z =390°

Step-by-step explanation:

FOR x:

90°+x=180°(Since x and 90° lies on straight line ,their sum will be equal to 180°)

x=180°-90°

x=90°

FOR y:

30°+90°=y (y is the sum of two opposite interior angle 30° and 90° ; therefore it is an exterior angle)

y= 120°

FOR z:

30°+z=180°(Since z and 30° lies on straight line ,their sum will be equal to 180°)

z=180°-30°

z=150°

NOW:

x+y+z=90° + 120° + 150°

         =390°
