Answer 2

Step-by-step explanation:

X = 40°

reason angle sum of a triangle is 180°

so

65+45+x= 180°

140° +x = 180°

x=180-140

x= 40°

Y = 80°

Vertically opposite angle to the A ...

Z = 60° ( Linear pair..)

the sum of angles in a straight line = 180..

So x+y+z =180..

40+80+z= 180

120+z= 180

z=180-120

z= 60° ...
