When the length of sides are given, you can use law of cosine to find the angles
Refer to this website for details
https://www.mathsisfun.com/algebra/trig-cosine-law.html

11^=8^2+5^2-2*8*5cosA
-80cosA=32
cosA=-0.4
A is about 114 degree
use the same method to find out B and C, you will get 42 and 25

To determine the answer for this, you need to divide the amount earned by hours worked to get how much she is paid per hour.
22.50/3 = 7.50
60.00/8 = 7.50
112.50/15 = 7.50
Your answer is A.) A = 7.50h, meaning $7.50 per hour.
I hope this helps!

at a restaurant the ratio of kids meals sold to adults meal was 5:4. if there were 20 kids meals sold, what is the combined amou
seraphim [82]
I would set up a proportion:

\frac{20}{x}=\frac{5}{4}

The proportion basically says, "if there are 5 kids meals for every 4 adult meals, that means 20 kids meals would mean x adult meals."  Just cross multiply and then solve for x:

\frac{20}{x}=\frac{5}{4}\\5x=80\\x=16

That means there are 20 kids meals sold and 16 adult meals sold, so the result is:

36 meals in total.

You are cutting as many 20 1/2-inch pieces from the board to make
zlopas [31]

Answer: The number of steps you can make is 5 pieces and \dfrac{35}{41}\ inch is left over.

Step-by-step explanation:

Since we have given that

Length of pieces from the board to make ladder steps for a tree fort = 20\dfrac{1}{2}\ inch=\dfrac{41}{2}

Length of board = 120 inch

Number of pieces from the board to make ladder steps for a tree fort is given by

120\div \dfrac{41}{2}\\\\=120\times \dfrac{2}{41}\\\\=\dfrac{240}{41}\\\\=5\dfrac{35}{41}

Hence, the number of steps you can make is 5 pieces and \dfrac{35}{41}\ inch is left over.
