Answer 2

Answer:

hence required angles are 150° and 30°

Step-by-step explanation:

let one angle ibe x

then other angle = 1/5 x

now sum of co interior angles when a line intersect at two distinct points on parallel lines

= 180°

now x + 1/5 x =180°

( 5x + x ) /5 = 180

6x. 180 × 5

x =. 900 /6

x = 150°

so first angle is 150°

then other angle = 1/5. × 150 = 30°

therefore the required angles are 150° and 30°
