Answer:

1:1:2 is the required ratio

Answer 2

Answer:

1:1:2

Step-by-step explanation:

SUM OF ALL ANGLES = 180

SUM OF BASE ANGLES + ANOTHER ANGLE = 180

90 + X  =  180

X = 180 - 90 = 90

IF WE TAKE BOTH BASE ANGLES EQUAL THEN

X + X + 90 = 180

2X = 180 - 90 = 90

X = 90/2

X = 45

THEREFORE BASE ANGLES = 45 , 45

RATIO OF ANGLES = 45:45:90

1:1:2 IS THE RATIO
