Answer 1

Question no: 12

Let the 55°angle=w

angle w + angle y = 180°
55°+angle y = 180°
angle y = 180° – 55°
angle y = 125°

angle y + angle x = 180°
125° + angle x = 180°
angle x = 180°–125°
angle x = 55°

angle x + angle z = 180°
55° + angle z = 180°
angle z = 180°– 55°
angle z = 125°

Question no: 13

sum of interior opposite angles = exterior angle
60°+60° = x
x =120°
