Answer 2

Step-by-step explanation:

The only thing you have to do is to remember the rule that Opposite angles of congruent sides are congruent i.e. equal

(i) x= 40°

(ii) x= 180-45+45= 90°

(iii) x= 50°

(iv) 180= 100+x+x

80=2x

x=40°

(v) 180=90+x+x

x= 45°

(vi) 180=40+x+x

x=70°

(vii) x=180-120

x= 60°

(viii) 180-110= 70

180= x+x+70

x= 55°

(ix) x=30° (Opposite angles)

The Property I applied in all equations is 180= angle a + x + x.
