Angle BDC is given as 38° but not drawn in the figure. Amateurs.

We calculate angle DBC

DBC = 180° - 96° - 38° = 180° - 134°

We won't bother subtracting because we're really after

angle ABD = 180° - DBC = 134°

Now we have a Law of Cosines situation,

AD² = AB² + BD² - 2(AB)(BD) cos ABD

AD = √( 5.8² + 27.3² - 2(5.8)(27.3) cos 134°)

AD ≈ 31.61 m

Answer: 31.6 m

City code says you need to have a total of at least 54 toilet stalls, but each bathroom can only have 6 stalls. How many bathroo

Lady bird [3.3K]

City code says you need to have a total of at least 54 toilet stalls, but each bathroom can only have 6 stalls.

So, Let the number of bathrooms to be built be = x

Number of toilet stalls needed = 54

Number of stalls each bathroom can have = 6

So, the number of bathrooms to be built are =

$6(x)=54$

$x=\frac{54}{6}$

$x=9$

Hence, one must build 9 bathrooms with 6 stalls each.
