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
