Step-by-step explanation:
{PART A}
65° and y are adjacent angles, which are equal, hence y=65°
x and y are also adjacent.
so 65°+65°+x+z= 360°
its because interior angles of a parallelogram add upto 360°
130°+x+z= 360°
360-130=230°, which is x and z
since they are equal, divide 230 by 2 = 115. so x and z is 115°
y= 65°
x=115°
y= 115°
{PART B}
180°-125°=55°
x= 55° because it's adjacent
full y= 125° because it alternates 125°
125-55= 70°
x= 125°
y= 70°
z= 70°
