Answer:
11.3 Km
Step-by-step explanation:
Consider the right triangle formed by AB and West.
The acute angle WAB = 270° - 250° = 20°
and West is the adjacent side of the right triangle with AB the hypotenuse
Using the cosine ratio in the right triangle, then
cos20° = 
= 
Multiply both sides by 12
12 × cos20° = adjacent
11.2763.. = adjacent, that is
B is 11.3 Km west of A
Answer:
17.2 units
Step-by-step explanation:
You would use the Pythagorean Theorem to solve. The height (a) is 4 units. The base (b) is 6 units.
4^2 + 6^2 = sqrt(52)
This would mean that the hypotenuse is 7.211102550927979 units or 7.2 units (the square root of 4^2 + 6^2).
Now you would need to just add all three sides.
6 + 4 + 7.2 = 17.2 units

Answer:
3sqrt2
Step-by-step explanation:
If a side length is a, then a^2 + a^2 = 36
2a^2 = 36
a^2 = 18
a = 3sqrt2
Or, you can remember that in a square, if you cut it in half diagonally, you get a 45-45-90 triangle, so the sidenglth is diagonal/sqrt2
