Theta has a reference angle of 30° and is in Quadrant I or II.
Sin(theta) = ½
Basic angle: 30
<h3>What is the reference angle?</h3>
The acute angle between the terminal arm/terminal side and the x-axis. The reference angle is always positive. In other words, the reference angle is an angle sandwiched between the terminal side and the x-axis.
Angles: 30,
180-30 = 150
Because sin is positive in quadrants 1 and 2.

$ 10
250 * 2 =300
5*2=10
So the answer is $ 10
4 kings total out of 52 cards
1 king was picked so 3 are left, 52 -1 = 51 cards left
so you have a 3/51 reduced to a 1/17 probability of picking another king
Answer: (5^3) / (5^7) = 5^ -4
or
1 / 5^4
