Answer:
12.7 cm
Step-by-step explanation:
ABC
12² = 6² + BC²
12² - 6² = BC²
144 - 36 = 108
CB² = 108
√108 = 10.392
CB = 10.392
CBD
Sin (55°) = CB / CD
0.81915 = √108 / CD
CD = 10.392 / 0.81915
CD = 12.686
CD = 12.7cm

Answer:
I would assume they drove a car.
If so, then Dallas to Houston: 239.3 miles.
Then, Houston to Austin: 165.3 miles
Shortest route back to Texas: 913.5.
<u>I used g o o g l e m a p s to find my answer.</u>
Now add the numbers up:
239.3+165.3+913.5= 1318.1
They traveled 1318.1 miles in all.
9514 1404 393
Answer:
False
Step-by-step explanation:
The terms of a geometric series would have a common ratio. The terms of this series do not. (The differences increase by 1 each time, so it is a quadratic series.)
False, the series is not geometric.
