Answer:
5.3
Step-by-step explanation:
Use the right triangle altitude theorem.
KM/KN = KL/KN
12/8 = 8/KN
1.5 = 8/KN
1.5KN = 8
KN = 8/1.5
KN = 5 1/3
Answer: 5.3
42 divided by -8 is -5.25 (-5 1/4)
I honestly don’t know man but don’t worry, if you get a bad score it won’t matter in 30 years :)
Answer:
4588 [in²].
Step-by-step explanation:
1) the given octagon can be imagined as 8 triangles (see the attachment). In order to calculate the required area of the octagon, it is enough to calculate the area of one triangle then increase it 8 times:
2) area of one triangle is:
37*31/2 [in²].
3) the required area of the octagon is:
31*37*8/2=31*37*4=4588 [in²].
That's a 2/6 probability, so 1/3 -- B.
