Answer:
The three angles are 84º, 30º, and 66º. You multiply the ratio 14:5:11 by 6º.
Step-by-step explanation:
The sum of a triangle's interior angles is 180º. From the information we know:
- 14xº+5xº+11xº=180º
- Combine like terms, 30xº=180º
- Divide, xº=6º
Now we can say that the three angles are 14(6)=84º, 5(6)=30º, 11(6)=66º.
