Answer:
a.∠a=105°
b.∠b=75°
c.∠c=105°
d.∠d=75°
e.∠e=105°
f.∠f=75°
g.∠g=105°
h.∠h=75°
Step-by-step explanation:
a.c ∠a=∠c x+70°=3x x=35° so ∠a=∠c=105°
{corresponding angles of parallel lines are equal}
b.∠a=∠o=180° ∠a=105° so ∠b=75°
{the angle of a line is 180°}
c.180=105
=75 {linear pair theorem}
d.∠c+∠d=180° ∠c=105° ∠d=75°
e.∠c=∠e=105°
{vertical angles are equal}
f.∠a=∠f=75°
g.∠g=∠a=105°
h.∠h=∠²b=75°
{vertical angles are equal}
