The solution is actually pretty simple. All you have to do is plug the numbers in corresponding the letters like a with a b with b and calculate
7). 6(6)+(5)^2-(3)^2=52
And you do the same thing with 8) you get 180
The chance of a king and a ace being drawn out of a deck of cards would be 8 out of 52
The complement of an angle is what, when added to it, equals 90 degrees (90°), so 90 - 76 = 14°
Alrighty (so what I did to find the answer is went to desmos and typed this equation in and then hit the bar thingy on the left and it turned it into a fraction)The awnser is B or 81/16
