Answer:
18 + √26
Step-by-step explanation:
You will have to use distance formula between all 4 points to solve this. Once you have found the lengths between the points, you can add them all together. When you add them all together you should get 18 + √26 as your answer.
Answer:
9.43miles
Step-by-step explanation:
distance travelled
5 miles west
8 miles south
in a straight line = (5^2 + 8^2)^0.5 =89^0.5 = 9.43miles
For the first question on the screenshot, you need to put this same exact order as I put it.
A D B C
Now the second question
A = 3 units
B = 4 units
C = 4 units
D = 3 units
9514 1404 393
Answer:
Step-by-step explanation:
With a single application of the Law of Cosines, you can only find one of an unknown side or an unknown angle. The other three elements in the 4-variable equation must be specified.
However, a single application of the LoC can be used to find DE. Then, knowing the three sides, either of the unknown angles can be found from an additional application of the LoC.
So, the answer is "it depends." It is yes to all if finding DE first is allowed. It is "no" to the angles if they must be found without finding DE first.
