we won´t have any triangle with these measures.
law of cosines.
a²=b²+c²-2bc(cosФ)
Data:
a=1
b=2
A=31º
Therefore:
1²=2²+c²-4c(cos 31º)
c²-(4cos 31º)c+3=0
4cos 31º≈3.43
We have to solve this equation, and find out the number of solutions:
c=[4cos 31º⁺₋√(11.756-12)]/2=
c=(4cos 31º⁺₋√(-0.244)/2
Because we have the square root of a negative number, we don´t have any possible solutions, that is to say , there are not real solutions for this equation.
Answer: We don´t have any triangle with these measures.
Answer:
28%
Step-by-step explanation:
do 28/28+72=28/100
then multiply 28/100 by 100 which equals 28%
The given information tells us that for every one flight Muddville has, Fly Low airlines will have 3. This means they have a 3:1 ratio
X = fly low airlines flight, Y = muddville airlines flights
3X + Y = 16
3 + 1 = 4
6 + 2 = 8
9 + 3 = 12
12 + 4 = 16
This means in one day, Fly low airport will have 12 flights while Muddville airport will have 4
Answer:
102
Step-by-step explanation:
The first step is to find out how to find the next number in the term.
In this we can see that to get to the next number in the term we need to add 5.
The easiest way to figure out the 21st term of this, would be to multiply 5×21. This is equal to 105.
But since we started at three less than 5, we need to subtract 3 from 105. 105-3=102.
The 21st term is 102.
