Me being a junior in high school and not knowing middle school math
10 tenths in a whole.....
The answer is 8km.
1:100,000 = 1.6 miles = 1 kilometer x 8 = 8 km
The height of your scale model will be 37.8cm.
1.26 x 30
Firstly, we can look at our givens,
a = 17
b = 22
c = 30
And we are looking for m∠A
Is the Law of Cosines. Now we can solve for our unknown, m∠A. This will give us
Now we can substitute in our given variables.
Then we can plug this into our calculator which will give us
34.19185257 degrees
Now we just have to round to the nearest tenth
This means that the answer is 34.2 degrees
