1) Find AC using either the distance formula or the Pythagorean Theorem.
kap26 [50]

Answer:

1.  C) 2/5 or 4.47   if 2/5 means 2 sqrt(5)

2. sqrt(68)

Step-by-step explanation:

1.  using the pythagorean theorem

a^2 + b^2 = c^2

where a = distance AB = 4   b = BC = 2   and c = AC = ?

4^2 + 2^2 = c^2

16 + 4 = c^2

20 = c^2

take the square root of each side

sqrt(20) = c

sqrt(4) * sqrt(5) = c

2sqrt(5) = c


2.  using the pythagorean theorem

a^2 + b^2 = c^2

where a = distance AC = 8   b = BC = 2   and c = AB = ?

8^2 + 2^2 = c^2

64 + 4 = c^2

68 = c^2

take the square root of each side

sqrt(68) = c

sqrt(4) * sqrt(17) = c

2sqrt(17) = c

did you forget to put the square root of B
