We are asked in the problem to find csc (13pi/6). first we can convert the radians angle first to degrees that is equal to 390 degrees. The terminal angle is 30 degrees. csc is the reverse of sin. sin 30 is equal to 1/2, positive since in the first quadrant. hence the answer is 2.
Solute = what is dissolved
solvent = that which dissolves or can dissolve
You take it from here.
The answer is 5 5/7-8 2/7=3 3/7
<span> i solved the problem by listing all the possible combinations (123, 124, 125...). But I have a feeling there's a shortcut to solving this problem.I think there is but you get the juist of it </span>
