Answer:
a. rad27
Step-by-step explanation:
we can use a2+b2=c2 where c is the hypotonuse.
we plug in 3^2+b2=6^2
9+b^2=36
b^2=27
then do a rad over each to get rid of the ^2 on the b
b=rad 27
answer is rad27
Use the law of sines:
Sin(angle) = Opposite Leg / Hypotenuse
Sin(30) = 14 / x
x = 14/sin(30)
x = 28
Answer:
Just list all the coefficients.
Step-by-step explanation:
one thing to know
If a variable is just there, like x, it's coefficient is always a one

Answer:
11 cans
Step-by-step explanation:
Since you know that the ceiling is in the shape of a square and each side is 55ft, you can multiply 55x55 to get 3075, which is divided by 275 due to the amount of paint in a can. It would result in 11 cans, but if it were a decimal like 11.3, then you would need 12 cans since you can't split a can.
