Question

Find the value of angle i, if the lines marked with arrows are parallel to each other​

Answer 1

Answer:

g= 75 (co interior angles)

h=20 (vertically opposite angles)

then I = 180 - g + h ( linear pairs)

I = 180- 75+20

I = 180 - 95

I =85 degrees

Answer 2

Answer:

75°

Step-by-step explanation:

(h+i)= (75 + 20)°. [exterior Angele= sum of the opposite Angeles of the adjacent angle]

h+i= 95°

as it is given lines marked with arrow are parallel

so

20°=h ( alternate interior angles)

so,

h+i=95°

20+i= 95°

i= 95-20

i= 75°
