11-18/-4
-7/–4=7/4
Answer:
Step-by-step explanation:
The smallest angle is opposite to the smallest side.
<u>Use the law of cosines to find the angle opposite to side with the length of 10 cm:</u>
- cos A = (b² + c² - a²)/(2bc)
- cos x = (11² + 13² - 10²)/(2*11*13)
- cos x = 190/286
- cos x = 0.664 (rounded)
- x = arccos (0.664)
- x = 48.4° (rounded)
Answer:
should be 13
Step-by-step explanation: 6.5 x 2
