Step-by-step explanation:
solution :-
y= 160°[vertically opposite angle ]
X=Z [vertically opposite angle]
we know that sum of angles all around if a point is equal to a complete angle i.e two straight line angles
therefore X+Y+Z+160° =360°
substituting the value of angles , we get:-
X+160°+X +160°=360°
using transposing to solve for x,
2x + 320° = 360°
2X= 40°
X=20°
therefore Z=X=20
so, the measures of X,Y and Z are:-
X=20°
Y=160°
Z= 20°
