Answer:
36° : 63° : 81°
Step-by-step explanation:
Firstly, add all the ratios
4 + 7 + 9 = 20
Now as we kniw that the total angles of a ttiangle are 180°, divide 180° by 20
180° ÷ 20 = 9°
Get back to the ratios now
4 : 7 : 9
= 4 × 9 : 7 × 9 : 9 × 9
= 36° : 63° : 81°
To crosscheck you can add the angles to check if their sum is 180°
36° + 63° + 81°
= 180°
