Answer:
Step-by-step explanation:
<u>Use the law of cosines:</u>
- cos C = (25² + 27² - 28²)/(2*25*27)
- cos C = 0.4222
- m∠C = arccos 0.4222
- m∠C = 65°

of 1km is 415 m
In every 1 kilometers = 1 000 meters
=> 415 / 1 000 – this is already a fraction , we need to convert it into its
simplest form
=> 415 / 1 000 = this will be divided by 5
=> 415 / 1 000 / 5/5 = 83 / 200
Thus, the fraction of 415 meter in 1 km is 83 / 200</span>
