since we know that,
the straight line make 180°
so,
angle x + 90°=180°.
x=180°-90°=x=90°•
angle z+30°=180°
z=180°-30°=z=150°.
angle x+z= 180°
90°+30°=120°
angle y+120°=180°•
y=180°-120°=y=60°
the straight line make 180°
so,
angle x + 90°=180°.
x=180°-90°=x=90°•
angle z+30°=180°
z=180°-30°=z=150°.
angle x+z= 180°
90°+30°=120°
angle y+120°=180°•
y=180°-120°=y=60°
