Answer:40° & 140° is the answer

Step-by-step explanation:as 40°&140° are in ratio of 2:7

Step-by-step explanation:RATIO = 2:7

THEN THE ANGLES ARE = 2x and 7x

SUPPLEMENTARY ANGLES ADD UPTO 180

THEN THE EQUATION FORMED IS –

2x + 7x = 180

9x = 180

x = 180/9

x = 20

THEN ANGLES ARE –

2x = 2 X 20 = 40

7x = 7 X 20 = 140

THE TWO SUPPLEMENTARY ANGLES ARE 40 AND 140
