Question

From adjoining figure find values of x,y,z
​

Answer 1

Answer:

y=40°(vertically opposite angle) Y+Z=180 (straight line) angle Z=180-Y ,Z=140 and Z=X (V.O. angle)

Answer 2

Answer:

angle y=40°(vertically opposite angles)

angle x+ angle y= 180°(linear pair)

x+ 40°=180°

x= 180°-40°

x=140°

angle z= angle x°(vertically opposite angles)

angle z=140°
