Answer:
1/13
Step-by-step explanation:
There are 4 king cards:
King of Hearts
King of Diamonds
King of Clover
King of Spades
This is 4 cards in a standard deck of 52. Set as a fraction 4/52.
Simplify:
(4/52)/(4/4) = 1/13
1/13 is the probability of drawing a KIng card.

The answer would be "-5/3+ <span>61/6."</span>
Remember to use KCC (Keep, Change, Change)
-2 1/3-(-10 1/6) (KCC) -2 1/3+10 1/6
-2 1/3=-5/3
&
10 1/6=61/6
Therefore the simplified answer is -5/3+ <span>61/6!

Answer is picture below. Sorry, they are not in order while being worked at but, they ate in order in the function.
That's basic trigonometry
Tangent 57 degrees = AC / 9
AC = Tangent 57 degrees * 9
AC = 1.5399 * 9
AC =

We need to put all elements in one side so that the other side is 0. Then, apply quadratic formula to solve the problem. To do that, we need to subtract both sides by 4.
