Answer:
a=-6
Step-by-step explanation:
2(3-a)=18
3-a=18/2
3-a=9
a=3-9
a=-6
Let’s first find the angle y
Angle y = 180-(140+10)(angle sum property)
Angle y = 180-150
Angle y = 30 degrees
Angle x = 180- 110 ( linear pair )
Angle x = 70
Angle z = 180-(70+90)( angle sum property)
Angle z = 180-160
Angle z = 20
X axis (-40,0)
y axis (0,15)
