Question

Give Answer of this ​

Answer 1

if angle 1 = 108°

angle 4 = 108°

angle 2 = 360° -108°×2/2

= 360°-216°/2

= 144°/2

= 72°

angle 3 = 72°

angle 5 = 72 °

Answer 2

Answer:

∠2=72°

∠3=72°

∠4=108°

∠5=72°

Step-by-step explanation:

i. Given that, ∠1=108°

∠5 = 180°–∠1= 72°

ii. Since ∠5=∠2 [opposite angles]

∠2 = 72°

iii. l || m

and t is transversal,

Therefore, ∠5=∠3=72° [similar angles]

iv. ∠4= 180°–∠3= 108°
